BREW-openclaw-cli-CVE-2026-35622 — OpenClaw: Google Chat app-url webhook auth accepted non-deployment add-on principals

Affected: Homebrew: openclaw-cli

## Summary Google Chat app-url webhook verification accepted add-on principals outside the intended deployment binding.

## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: < 2026.3.22 - Fixed: >= 2026.3.22 - Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`) - Latest published npm version checked: `2026.3.23-2`

## Fix Commit(s) - `a47722de7e3c9cbda8d5512747ca7e3bb8f6ee66`

## 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.

OpenClaw thanks @ijxpwastaken for reporting.
