fix(#7241): require X-Api-Key header for mood signal writes (authenticated) by Yzgaming005 · Pull Request #7537 · Scottcjn/Rustchain

Yzgaming005 · 2026-06-22T09:15:46Z

Summary

The POST /api/v1/agents/{name}/mood/signal endpoint accepted mood-affecting signals from any unauthenticated caller. An attacker could poison any agent's mood history, steering generated titles, comments, and posting probability — a state-changing cross-agent integrity issue.

Changes

bottube_mood_engine.py — added _require_mood_signal_auth() with hmac.compare_digest constant-time comparison
bottube_mood_engine.py — record_mood_signal() now requires X-Api-Key header matching MOOD_SIGNAL_API_KEY env var
bottube_mood_engine.py — fail-closed: returns 503 when env var is not configured (no silent open-door)
tests/test_bottube_mood_routes.py — added 7 new tests covering all auth states

Why this approach

Constant-time comparison (hmac.compare_digest) defeats timing attacks
Fail-closed: if the operator forgets to set MOOD_SIGNAL_API_KEY, the endpoint returns 503 instead of silently accepting writes
Granular: only the mutation endpoint (/mood/signal) is protected; read-only endpoints remain public — no unnecessary auth friction for existing consumers

Testing

python3 -m pytest tests/test_bottube_mood_routes.py -v — 7/7 passed
Auth scenarios covered: missing env var (503), missing header (401), wrong key (403), valid key (200)
Public endpoints verified: no auth required for GET /mood, POST /mood/title

Trade-offs

No rate limiting on the auth check itself (future work: add per-IP rate limiter for /mood/signal)
API key is static per deployment; rotation requires restart (acceptable for current scale)

Closes #7241

…ence

- Add _require_mood_signal_auth() with constant-time comparison (hmac.compare_digest) - Fail-closed when MOOD_SIGNAL_API_KEY env var is not set (503) - Public read endpoints (/mood, /mood/title, /mood/comment) remain unprotected - Add 7 focused tests: missing key, missing header, wrong key, valid key, weight validation, and public endpoint accessibility Closes Scottcjn#7241
