  "summary" : "OpenClaw Google Chat shared-path webhook target ambiguity allowed cross-account policy-context misrouting",
  "details" : "## Summary\nWhen multiple Google Chat webhook targets are registered on the same HTTP path, and request verification succeeds for more than one target, inbound webhook events could be routed by first-match semantics. This can cause cross-account policy/context misrouting.\n\n## Affected Packages / Versions\n- npm: `openclaw` <= 2026.2.13\n- npm: `clawdbot` <= 2026.1.24-3\n\n## Details\nAffected component: `extensions/googlechat/src/monitor.ts`.\n\nBaseline behavior allowed multiple webhook targets per path and selected the first target that passed `verifyGoogleChatRequest(...)`. In shared-path deployments where multiple targets can verify successfully (for example, equivalent audience validation), inbound events could be processed under the wrong account context (wrong allowlist/session/policy).\n\n## Fix\n- Fix commit (merged to `main`): `61d59a802869177d9cef52204767cd83357ab79e`\n- `openclaw` will be patched in the next planned release: `2026.2.14`.\n\n`clawdbot` is a legacy/deprecated package name; no patched version is currently planned. Migrate to `openclaw` and upgrade to `openclaw >= 2026.2.14`.\n\n## Workaround\nEnsure each Google Chat webhook target uses a unique webhook path so routing is never ambiguous.\n\n## Release Process Note\nThe advisory is pre-populated with the planned patched version. After the npm release is published, the remaining action should be to publish the advisory.\n\nThanks @vincentkoc for reporting.\n\n---\n\nFix commit 61d59a802869177d9cef52204767cd83357ab79e confirmed on main and in v2026.2.14. Upgrade to `openclaw >= 2026.2.14`.",
