Release Status

The fix shipped in v2026.3.22 and remains present in v2026.3.23 and v2026.3.23-2.

Code-Level Confirmation

extensions/googlechat/src/auth.ts now requires expectedAddOnPrincipal matching for add-on principals and rejects unexpected issuers.
extensions/googlechat/src/monitor-webhook.ts passes the configured appPrincipal into auth verification for the shipped webhook path.
