Two related redaction bugs from #43083:
1. build_assistant_message redacted tool-call arguments in-memory. That dict
feeds both the replayed conversation history and state.db (which is itself
replayed verbatim on session resume), so the model read back its own
PGPASSWORD='***' psql call and copied the placeholder, breaking every
credential-dependent command on the second turn. The masking gave no real
protection either — the same secret still leaks through tool OUTPUT. Remove
it. Keeping secrets out of the replayable store is a separate
tokenization/vault concern (security.redact_secrets still governs
storage-time redaction elsewhere).
2. _AUTH_HEADER_RE's greedy \S+ credential class ate a closing quote when the
token sat flush against it (Authorization: Bearer sk-.."), turning value
corruption into syntax corruption (unterminated quote -> shell EOF /
SyntaxError). Exclude " and ' from the token class; real credentials never
contain them.
Closes#43083.
Config-backed quick_commands bypassed the admin-only slash gate. The
early gate in _handle_message only fires for registry-known commands
(is_gateway_known_command), but quick_commands are never in the gateway
registry, so they reached the type:exec dispatch sink unchecked. An
allowlisted non-admin gateway user could invoke admin-only quick
commands — including shell exec in the gateway process — even when the
operator set allow_admin_from / user_allowed_commands to lock them out.
Apply _check_slash_access(source, command) at the quick_commands
dispatch site (the single exec chokepoint, cold-path only) using the
raw typed name. Admins and users with the command in
user_allowed_commands still run it; backward-compat (no policy set)
is unaffected.
Fixes#44727.

* fix(dashboard): close PTY WebSocket on child EOF to stop FD leak
The /api/pty handler's reader task returns on child EOF, but the writer
loop stayed blocked on ws.receive() until the browser sent a disconnect.
When the browser socket is half-open (no FIN delivered — common on
macOS/launchd), that disconnect never arrives, so the handler never
reaches its finally and the PTY master fd + child process leak. With
dashboard auto-reconnect (#52962), every dropped socket then spawns a
fresh PTY on top of the orphaned one, exhausting file descriptors within
hours (EMFILE / Errno 24).
Fix: the reader task now closes the WebSocket in a finally when the child
EOFs or the send side breaks, which unblocks ws.receive() so the existing
finally runs bridge.close(). The writer loop also guards ws.receive()
against the RuntimeError Starlette raises once the socket is closed.

The snapshot/vision guards re-check the page URL before returning content,
but browser_console(expression=...) -> _browser_eval returns arbitrary JS
results directly, leaving two same-class bypasses open:
1. Direct fetch: fetch('http://127.0.0.1/secret').then(r=>r.text()) reads
a private endpoint and returns the body — the page URL stays public so
the post-eval recheck never sees it.
2. Navigate-then-read: location.href='http://127.0.0.1/' then a later eval
reads document.body.innerText.
Guard _browser_eval on the same condition as navigate/snapshot/vision
(not local backend, not local sidecar, not allow_private_urls):
- pre-scan the expression for private/always-blocked URL literals
- re-check window.location.href after the eval at both success-return
sites (supervisor fast-path + subprocess fallback)
Probe failures fail-open (matching the snapshot/vision guards).
The private-network guard in browser_snapshot() and browser_vision()
blocked all private URLs, including those accessed via local sidecar
sessions (hybrid routing). Local sidecar sessions intentionally access
private URLs — the cloud provider never sees the URL in that case.
Add `_is_local_sidecar_key(effective_task_id)` check to both guards,
matching the existing pattern in browser_navigate().
Fixes#45101 review feedback from egilewski.
The SSRF bypass in #44731 was only patched for browser_snapshot(), but
browser_vision() exposes the same vulnerability — it takes a screenshot
and sends it to the vision model without checking if eval-driven
navigation moved the page to a private/internal URL.
Add the same current-page URL safety check to browser_vision() before
any screenshot is captured, encoded, or forwarded to the vision model.
This covers both the normal screenshot path and the Lightpanda Chrome
fallback path.
7 new tests: blocks private URL, allows public URL, skips in local
backend, skips when private URLs allowed, handles eval failure/empty/exception.
browser_snapshot() now checks the current page URL before returning
content. When browser_console() changes location.href to a private or
internal address (e.g., http://127.0.0.1:8080/), the snapshot returns
an error instead of exposing the private page content.
This closes the SSRF bypass where an attacker could:
1. Navigate to a public page
2. Use browser_console to eval location.href = 'http://127.0.0.1:port/'
3. Use browser_snapshot to read the private page content
The fix reuses the existing _is_safe_url() and _allow_private_urls()
infrastructure, and fails open if the URL check itself fails.
Fixes#44731
HolographicMemoryProvider.shutdown() dropped its MemoryStore reference
without calling the existing MemoryStore.close(). Since the connection is
opened check_same_thread=False (one per session), its fd was released by
refcount/GC at a non-deterministic time on a non-deterministic thread,
churning a DB fd through the kernel free pool on every session teardown.
Call close() so the fd is released deterministically.
Reported by @alfranli123 (#44037), who pinpointed the exact code location.
Note: the report's TLS-fd-recycle corruption attribution could not be
reproduced from the code — dropping a sqlite connection flushes valid
SQLite pages via the VFS, never TLS framing, and the provider is at most a
releaser of DB fds, not a TLS-flushing socket owner. This change is correct
resource hygiene that removes per-session fd churn regardless.
A hard gateway crash (exit code 1) skips the graceful shutdown path, so
sessions.json is never cleared and is left pointing at sessions already
ended in state.db. On the next startup get_or_create_session() reuses
those stale entries as long as the time/policy reset checks pass — it
never consults end_reason — so every incoming message is silently routed
into a closed session, with no log or error (#52804).
SessionStore._ensure_loaded_locked() now calls a new
_prune_stale_sessions_locked() that drops any entry whose session_id has
end_reason IS NOT NULL in state.db. Idempotent, _db=None / legacy-absent
safe, DB errors non-fatal, sessions.json rewritten only when something
was pruned. Self-heals into a fresh session on the next message.
Reported and diagnosed by @terry197913 (#52808).
#35994 moved /new reset cleanup off the loop, but _cleanup_agent_resources
(agent.close() subprocess teardown; shutdown_memory_provider() plugin IO) was
still called INLINE on the event loop from three other sites:
- _session_expiry_watcher (5-min idle sweep) — live loop
- _handle_message_with_agent cache-hygiene re-eviction — live loop
- _finalize_shutdown_agents / stop() idle-cache loop — shutdown
A wedged memory provider on any of these froze the loop: bot goes silent,
runtime-status updated_at heartbeat stops advancing, and SIGTERM can't be
serviced (requires kill -9) — exactly the #53175 zombie pattern.
Adds _cleanup_agent_resources_off_loop: a bounded (30s) worker-thread offload
mirroring the #35994 reset fix, and routes all four sites through it.
The system-prompt backend probe imported a nonexistent symbol —
`from tools.environments import get_environment` — which always raised
ImportError: cannot import name 'get_environment'. The exception is caught
and only drops the live backend description to a static fallback, so it is
cosmetic, but it broke the live OS/user/cwd probe for every non-local
backend (docker/singularity/modal/daytona/ssh).
The real factory is `_create_environment` in tools.terminal_tool. Build the
environment the same way the live terminal path does (select backend image,
assemble ssh/container config from _get_env_config()), then run the probe.
Note: this does NOT affect tool loading — tool selection runs each tool's
check_fn and never consults this probe. Regression from #52147 (2026-06-25).
Closes#53667 (probe import); the 'cronjob-only' tool-collapse symptom is
not reproducible — tool selection has no probe dependency and memory's
check_fn is unconditionally True.
* test(ci): raise per-file timeout 140s to 300s to stop false timeouts
The per-file parallel runner caps each test-file subprocess at a flat
wall-clock budget. Combined with per-test subprocess isolation (a fresh
Python process per test), a large-collection file pays N x (interpreter
startup + import) of overhead before any test logic runs. That overhead
dilates under load on shared CI runners, so a file that finishes in
~100s on a quiet box can blow the old 140s cap purely from scheduling
jitter, surfacing as a false 'no tests ran' timeout (rc=124) with zero
actual test failures.
Raise the default to 300s (5 min). The Docker build matrix jobs already
take 7-10 min, so this headroom costs nothing on total CI wall time
while still bounding a genuinely hung file.

Two Windows-only desktop boot bugs that caused spurious reinstall/repair loops:
1. findOnPath() searched the empty extension BEFORE PATHEXT, so an
extensionless Git-Bash `hermes` shim shadowed the real hermes.cmd/.exe.
The shim then failed the shell:false --version probe and the resolver
fell through to bootstrap/repair even though a working CLI was on PATH.
Fix: try PATHEXT extensions first, keep the empty entry LAST so callers
that already include the extension (py.exe, pwsh.exe) still resolve.
2. handOffWindowsBootstrapRecovery() chose the destructive --repair over the
gentle --update by checking only venv\Scripts\hermes.exe -- the setuptools
console-script shim, written at the END of venv setup and absent in
interrupted/quarantined states. Fix: take --update when ANY real-install
signal is present (venv python, the shim, or .hermes-bootstrap-complete).
Adds windows-hermes-resolution.test.cjs (source-assertion pattern, wired into
test:desktop:platforms) guarding both regressions.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
A broken/empty Windows launcher venv can see the source tree via PYTHONPATH
but lack PyYAML, so 'import hermes_cli' succeeds while the first real CLI
import dies — the desktop then trusts the bootstrap marker, spawns a dead
backend, and loops on 'gateway offline' (#52378).
- backend-probes.cjs: canImportHermesCli now runs 'import yaml; import
hermes_cli.config' (extracted as hermesRuntimeImportProbe) and accepts an
env override, so a dependency regression is caught without a real broken
venv fixture.
- main.cjs: isBootstrapComplete() routes through new isActiveRuntimeUsable(),
which requires the venv python to pass the runtime import probe (with
ACTIVE_HERMES_ROOT on PYTHONPATH) — not just exist on disk.
Salvaged from PR #38179. The PR's install.ps1 reset/clean + autocrlf changes
and their tests are dropped: current main already preserves dirty checkouts
via stash (the data-loss-safe #38542 path) rather than the PR's older
reset-based Repair-ManagedCheckoutBeforeUpdate approach.
Add two tests for the self-lock guard in _recover_from_interrupted_install:
one asserting it clears the marker and skips install when hermes.exe is a
process ancestor (breaking the #52378/#45542 loop), one asserting it falls
through to a normal recovery install when the shim is NOT an ancestor.
The guard's manual-recovery hint runs only inside the Windows branch, so
quote it for cmd.exe (cd /d, double-quoted paths) — the cross-platform
fallback hint at the end of the function is left POSIX-correct.
Map Icather in scripts/release.py AUTHOR_MAP for the salvage.
Rebase onto plugins/platforms/matrix/adapter.py (code moved from
gateway/platforms/matrix.py). Same logic: _on_invite checks is_direct
on invite events and calls _record_dm_room to persist in m.direct
account data.
Fixes#44679
When the Desktop forcibly closes its WebSocket mid-write, asyncio logs a
full traceback for every pending connection-lost callback — 50+ identical
WinError 10054 (ConnectionResetError) lines per disconnect on Windows, the
equivalent ConnectionResetError/BrokenPipeError on POSIX. These are not
actionable: they are the expected side effect of the peer hanging up before
our writes drained.
Install a loop exception handler on the gateway serving loop that collapses
exactly this teardown class (ConnectionResetError/ConnectionAbortedError/
BrokenPipeError originating from _call_connection_lost) to a single debug
line, forwarding every other loop error to the existing/default handler
unchanged so genuine loop bugs still surface. Idempotent per loop.
The atomic mv approach (kyssta-exe's commit) narrows but does not close the
#38249 race: the temp name used $$ (parent shell PID), which is identical
across &-launched concurrent subshells. Two concurrent writers pick the same
temp file, clobber each other mid-write, and mv then publishes a torn snapshot
— a reader sourcing it absorbs declare-x/export fragments into PATH.
- Use $BASHPID (actual per-subshell PID) so concurrent writers never collide.
- Chain mv on export success (&&) and rm the temp on failure so a partial dump
never replaces a good snapshot; apply the same to the init_session bootstrap.
- shlex-quote the static temp-path portion (Windows/spaces), $BASHPID outside.
- LocalEnvironment.cleanup sweeps orphaned snap.tmp.* temps.
- Regression tests: string-shape + a behavioral concurrent writers/readers test
that proves the snapshot never tears (would still tear with $$).
Fix race condition in terminal environment snapshots that could corrupt
PATH with declare -x entries. When concurrent terminal calls share the
same snapshot file, the non-atomic 'export -p > snapshot.sh' write could
be read mid-write by another process, causing partial/corrupted env vars
to be sourced and mixed into PATH.
The fix uses atomic file replacement:
- Write to a temp file: export -p > snapshot.sh.tmp.303651
- Atomically replace: mv -f snapshot.sh.tmp.303651 snapshot.sh
On POSIX, mv within the same filesystem is atomic, so source() will
either see the old complete snapshot or the new complete one, never a
partial/truncated file.
Fixes#38249
- read_text(encoding='utf-8') (PLW1514)
- # windows-footgun: ok on signal.SIGKILL — module is Linux-only (reads
/proc, /sys/fs/cgroup; runs from a systemd unit)
- test lambda accepts the new encoding kwarg
Long-lived helpers spawned indirectly by tool calls (adb, platform
bridges) were left in the service cgroup after the gateway's main
process exited. When the kernel rejected the deferred cgroup-wide kill
with EINVAL, systemd blocked Restart=always for 6+ minutes, taking
down all platforms and cron windows (#37454).
Add a small ExecStopPost helper (gateway.cgroup_cleanup) that walks
cgroup.procs and sends per-PID SIGKILLs — a different kernel code path
than cgroup.kill, so it succeeds where the cgroup-wide write failed.
KillMode=mixed is preserved so the gateway still reaps its own
tool-call children before systemd intervenes (#8202).

When tools.environments.local can't be imported (partial install,
import-time error), _is_hermes_provider_credential() returned False —
fail-open. A skill could then register a Hermes provider credential
(ANTHROPIC_API_KEY, etc.) as env passthrough; _scrub_child_env lets
passthrough vars bypass the secret-substring net (rule 1), so the
operator's real key would land in the execute_code child. Reopens the
GHSA-rhgp-j443-p4rf bypass.
Fail closed instead: on import failure, treat the name as a protected
provider credential and refuse passthrough. Regression test exercises
the full register -> scrub path under a simulated import failure.

Follow-up to the salvaged #37733 fix. The contributor centralized
redaction at _openai_error and the chat/responses failure paths, which
covers the OpenAI-compatible envelopes transitively. Two sibling classes
crossed the same authenticated HTTP boundary unredacted:
- 8x cron-management endpoints returning {"error": str(e)} on 500
- the session-chat SSE error event ({"message": str(exc)})
Route both through the same _redact_api_error_text(force=True) helper.
Add AUTHOR_MAP entry for coygeek and a TestRedactApiErrorText guard
covering mask/force/limit/passthrough behavior.
Force API-server error text through the existing secret redactor before returning OpenAI-compatible errors, response fallback text, response snapshots, and run failure events. This prevents credential-shaped provider failure text from crossing the API-server boundary while preserving debuggable sanitized messages.
Extend the gateway noisy-status filter beyond Telegram so internal
compression lifecycle messages stay in logs instead of spamming Discord,
Slack, and other messaging channels.
Add an _is_user_authorized E2E for the platforms/whatsapp/session layout
on top of fesalfayed's resolver fix (#36665) — guards the actual
silently-dropped-LID-sender path from #36664.
expand_whatsapp_aliases hardcoded get_hermes_home()/whatsapp/session, but
the adapter writes lid-mapping files via get_hermes_dir("platforms/whatsapp/
session", "whatsapp/session"). On installs without the legacy directory the
two paths diverge, so the resolver finds no mappings and returns the bare LID,
which misses the allowlist and silently drops the message. Resolve through the
same helper so both sides stay in lockstep on new and legacy layouts.
When an LLM API call returns HTTP 4xx with an empty parsed SDK `body` ({}),
`_summarize_api_error` fell through to a bare `str(error)`, so users saw only
"HTTP 400" with no provider detail (reported on Windows in #36109). The SDK
leaves `body` empty in this case, but the httpx `response` still carries the
payload in `.text`.
- run_agent.py `_summarize_api_error`: when `body` is empty, fall back to
`response.text` — parse a JSON `error.message`/`message` when present, else
surface the raw (truncated) body. Platform-agnostic diagnostics.
- hermes_cli/oneshot.py: `hermes -z` now runs via `run_conversation` and returns
exit code 2 when the run is failed/partial with no usable final response, so
scripts can detect LLM failures (still 0 when a response — incl. an error
summary as output — is produced).
Tests: new tests/run_agent/test_summarize_api_error.py (empty-body JSON + raw
text, RED/GREEN verified) + oneshot exit-code/`run_conversation` wiring tests.
NOTE: #36109's original root cause (Windows "all providers return empty 400")
is not reproducible on current main (heavy provider-transport churn since
v0.15.1). This change does not claim to fix that root cause — it makes any
empty-body API error LEGIBLE so a future occurrence shows the real provider
message instead of a bare HTTP 400. Relates to #36109 (does not close it).
Follow-up on #54032 for #35166:
- Gate the PLAYWRIGHT_HOST_PLATFORM_OVERRIDE retry on the host being an apt
release newer than Playwright recognizes (Ubuntu >24.04 / Debian >13) via
playwright_host_unrecognized(), instead of retrying on ANY install failure.
A network/disk/permission failure on a supported host now surfaces unchanged
rather than getting a mismatched-glibc build forced onto it.
- detect_os() now captures DISTRO_VERSION from os-release.
- Fold in the interruptibility fix (was PR #35304, self-closed): wrap the
download in 'timeout --foreground -k 10' (probed, with plain-timeout
fallback) so a terminal Ctrl+C reaches the child and a wedged download is
force-killed after the deadline.
- Add behavioral tests that source the helpers and assert the retry fires only
on Ubuntu 26.04 / Debian 14, not on supported hosts, non-apt distros,
native-success, operator-pinned override, or unsupported arch.
On apt releases newer than the bundled Playwright recognizes (Ubuntu 26.04,
Debian 14, and future distros), 'npx playwright install --with-deps chromium'
hangs uninterruptibly at 'Installing Playwright Chromium with system
dependencies' because Playwright's resolver maps the host to a platform with
no download build (#35166).
Wrap every installer Playwright call in run_playwright_install(), which tries
the native install first and, only if it fails or times out, retries once with
PLAYWRIGHT_HOST_PLATFORM_OVERRIDE pinned to the newest known build
(ubuntu24.04-<arch>). This is the escape hatch Playwright's maintainers bless
for unrecognized platforms (microsoft/playwright#33434).
Try-native-first (not a hardcoded distro/version table) is deliberate:
- Self-correcting — when Playwright already supports the host (e.g. Ubuntu
26.04 on Playwright >=1.61) the first attempt succeeds and the override is
never applied, so we never force a mismatched-glibc build onto a release
Playwright handles correctly (microsoft/playwright#35114).
- Zero-maintenance — new distro releases work the moment Playwright adds them.
- Covers Debian 14+ and future releases, not just Ubuntu 26.04.
An operator-set PLAYWRIGHT_HOST_PLATFORM_OVERRIDE is always respected (applied
to the first attempt; retry skipped). Non-x64/arm64 arches have no fallback
build and skip the retry.
Refs #35166
A custom_providers config that names the model under model.name (or
model.model) resolved to an empty model, so the API request went out
with model= — HTTP 400 from OpenAI-compatible backends. Display paths
(hermes status/dump) already read model.name and showed the model,
making the failure silent.
The model id was read via 'default or model' at ~14 independent sites
(cli, gateway, cron, curator, oneshot, fallback, profiles, ...), none
of which honored 'name'. Rather than patch every site, canonicalize at
the single load/save chokepoint: _normalize_root_model_keys() now
promotes model.model/model.name -> model.default (precedence
default > model > name) and drops the stale alias, so every reader —
present and future — sees a populated default and config.yaml is
migrated canonical on next save. The gateway, which bypasses
load_config(), replays the same normalization in _load_gateway_config().

Dashboard /chat spawns the TUI attached to the dashboard's in-memory
gateway via HERMES_TUI_GATEWAY_URL. In that attach mode the already-running
gateway replays `gateway.ready` (and `session.info`) the instant the socket
connects, so those events land in GatewayClient.bufferedEvents *before* the
consumer's mount-time subscribe effect (useMainApp.ts) calls drain().
drain() then emitted the buffered events synchronously, so the
`gateway.ready` handler's patchUiState / setHistoryItems cascade ran while
React was still inside the first commit — tripping "Too many re-renders"
(Minified React error #301) and breaking Dashboard chat after `hermes update`.
Spawn / inline / sidecar modes never hit this: their `gateway.ready` only
arrives after the Python child boots, on a later async tick.
Fix: drain() defers the replay to the next microtask AND keeps `subscribed`
false until that microtask runs. Keeping `subscribed` false in the gap means
any live event arriving before the flush keeps buffering (publish() pushes
when !subscribed) instead of emitting synchronously and jumping ahead of the
chronologically-earlier replayed events — the flush re-drains the buffer
right after flipping `subscribed`, preserving FIFO order. A drainGeneration
token (bumped in resetStartupState) makes a queued flush a no-op if the
transport was reset/killed in the meantime, avoiding use-after-teardown and
duplicate/reordered exits.
Regression tests: (1) drain() does not dispatch buffered events synchronously;
(2) a live event arriving in the post-drain / pre-microtask window still
delivers BEHIND the earlier-buffered event (FIFO). Both are red against the
old synchronous behavior, green with this fix. Same class of fix as #44528.
Closes#36658
* fix(telegram): clear send_path_degraded on successful reconnect
_send_path_degraded was cleared only in _verify_polling_after_reconnect,
60s after reconnect and only if scheduled. A clean start_polling() reconnect
left the flag stuck True, short-circuiting send() and blocking all outbound
messages until the deferred probe ran (or forever if it never did).
Clear the flag the moment start_polling() succeeds — that is the recovery
signal. The deferred probe remains a defensive re-check that re-enters the
reconnect ladder (re-setting the flag) if it detects a silent wedge.
Fixes#35205.

Secret redaction is display/output-scoped on main — write_file writes
content verbatim, terminal/execute_code redact only output not the
command/source. The real bug is in displayed tool OUTPUT (read_file,
terminal, execute_code):
_DB_CONNSTR_RE's password group [^@]+ was greedy across newlines, so on a
multi-line block it scanned past the DSN line to the next stray '@' (a
Python @decorator), replacing every intervening character — including line
breaks — with ***. That dropped lines and concatenated the next line onto
the f-string line, making read_file output look corrupted (the file on disk
was always correct). Reported in #33801.
Fix:
- Forbid whitespace in the userinfo/password groups ([^:\s]+ / [^@\s]+) so
the match can never span a line break. A real DSN password never contains
whitespace. This alone kills the catastrophic line-dropping.
- Under code_file=True, preserve a password group that is a pure {...} brace
expression — f"postgresql://{user}:{pass}@{host}" is an f-string template,
not a live credential. Literal passwords are still masked.
- Pass code_file=True at the terminal and execute_code output redaction call
sites (file_tools already did) so code-execution output isn't corrupted by
ENV/JSON/template false positives. Real prefixes, auth headers, JWTs, and
private keys are still redacted.
Verified E2E against the reporter's exact pydantic-settings module: file
written verbatim, read_file shows the DSN f-string + @model_validator intact
with zero *** corruption, while a literal postgresql://admin:pw@host DSN and
a real sk- key are still masked.
