Summary
Google Chat allowlisting supports matching by sender email in addition to immutable sender resource name (
users/<id>). This weakens identity binding if a deployment assumes allowlists are strictly keyed by immutable principals.Affected Packages / Versions

Details
Affected component:
extensions/googlechat/src/monitor.ts
The
allowFrom checks accept:- Immutable sender id (
users/<id>) - Raw email (
alice@example.com) for usability
Historically,
users/<email> was also treated as an email allowlist entry. This is now deprecated because it looks like an immutable ID but is actually a mutable principal.Security Triage (2026-02-14)
Severity: Low
Rationale:
- Requests are authenticated as coming from Google Chat (token verification), so this is not a generic unauthenticated spoofing vector.
- A realistic exploit generally requires Google Workspace / IdP administrative control over identity lifecycle (e.g. reassigning an email address to a different underlying account) to obtain the same email with a different
users/<id>. - With that level of access, the attacker typically has broader compromise paths.
We still treat it as a valid defense-in-depth report because accepting mutable principals in authorization decisions can increase risk in chained-failure scenarios.
Remediation / Behavior Changes
Goal: preserve usability while reducing footguns.
- Raw email allowlists remain supported.
users/<email>is deprecated and treated as a user id, not as an email allowlist.- Documentation recommends
users/<id>when strict immutable binding is required.
