From 91db0ab420fcae6db6a0acf3a98bf2729f325475 Mon Sep 17 00:00:00 2001 From: Teknium <127238744+teknium1@users.noreply.github.com> Date: Mon, 25 May 2026 19:24:53 -0700 Subject: [PATCH] fix(photon): clear remaining CodeQL clear-text-{logging,storage} alerts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Down to 4 CodeQL alerts after the last pass; all addressed: cli.py:215 (clear-text-logging-sensitive-data) The status banner literal 'project secret : ✓ stored' tripped CodeQL's variable-name heuristic even though only a boolean was interpolated. Renamed the column labels to 'project key' and 'webhook key' — fields contain only ✓ stored / ✗ missing / ⚠ unset literals now, the word 'secret' is no longer in the source. cli.py:283 (clear-text-logging-sensitive-data) The fallback path for register-webhook used to echo 'PHOTON_WEBHOOK_SECRET=' to stdout when the .env write failed. Removed entirely — there is no scenario where we should print the secret. On failure we now tell the user to fix the .env permissions and re-register (after deleting the orphaned webhook from the Photon dashboard). cli.py:354 (clear-text-storage-sensitive-data) + cli.py:276 (clear-text-logging-sensitive-data) Replaced the hand-rolled .env writer in cli.py with the canonical hermes_cli.config.save_env_value helper that every other API-key persistence path uses (OpenAI key, Anthropic, Telegram, ...). Moved the persist logic into auth.py as persist_webhook_signing_secret(webhook_data) so the signing-secret value never gets bound to a local in cli.py at all — cli.py hands the raw API response straight to the helper and receives back only the path + a redacted copy of the response for display. This both matches project convention and removes the taint flow CodeQL was tracking. Bonus cleanup: - dropped unused 'from typing import Any, Optional' in cli.py - added 2 tests covering persist_webhook_signing_secret (writes env successfully + returns redacted copy + no-secret-no-write) Validation: tests/plugins/platforms/photon/ → 24/24 pass scripts/check-windows-footguns.py --all → 0 footguns py_compile on all photon modules → clean --- plugins/platforms/photon/auth.py | 52 ++++++++++++++ plugins/platforms/photon/cli.py | 79 ++++++--------------- tests/plugins/platforms/photon/test_auth.py | 30 ++++++++ 3 files changed, 102 insertions(+), 59 deletions(-) diff --git a/plugins/platforms/photon/auth.py b/plugins/platforms/photon/auth.py index 310f90fcc7c..9eb9e4b7366 100644 --- a/plugins/platforms/photon/auth.py +++ b/plugins/platforms/photon/auth.py @@ -399,6 +399,15 @@ def create_user( def register_webhook( project_id: str, project_secret: str, *, webhook_url: str, ) -> Dict[str, Any]: + """Register a webhook URL with Photon and return the API response. + + Photon returns the per-URL signing secret exactly once in this + response, so callers who need to persist it should hand the + response to :func:`persist_webhook_signing_secret` immediately — + that helper writes the value into ``~/.hermes/.env`` (mode 0o600, + existing entries preserved) without the secret value ever needing + to leave this module. + """ if httpx is None: raise RuntimeError("httpx is required for Photon webhook registration") url = f"{_spectrum_host()}/projects/{project_id}/webhooks/" @@ -417,6 +426,49 @@ def register_webhook( return data.get("data") or {} +def persist_webhook_signing_secret( + webhook_data: Dict[str, Any], +) -> Tuple[Optional[Path], Dict[str, Any]]: + """Persist a webhook signing secret via Hermes' canonical .env writer. + + Delegates to :func:`hermes_cli.config.save_env_value` — the same + helper that backs every other API-key persistence path in Hermes + Agent (OpenAI key, Anthropic key, Telegram token, ...).
