      <title>BREW-openclaw-cli-GHSA-chm2-m3w2-wcxm — OpenClaw Google Chat spoofing access with allowlist authorized mutable email principal despite sender-ID mismatch</title>
      <link>https://db.gcve.eu/vuln/brew-openclaw-cli-ghsa-chm2-m3w2-wcxm</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Homebrew: openclaw-cli&lt;/p&gt;
&lt;p&gt;### Summary
Google Chat allowlisting supports matching by sender email in addition to immutable sender resource name (`users/&amp;lt;id&amp;gt;`). This weakens identity binding if a deployment assumes allowlists are strictly keyed by immutable principals.&lt;/p&gt;
&lt;p&gt;### Affected Packages / Versions
(As of 2026-02-14; based on latest published npm versions)
- `openclaw` (npm): `&amp;lt;= 2026.2.13`
- `clawdbot` (npm): `&amp;lt;= 2026.1.24-3`&lt;/p&gt;
&lt;p&gt;### Details
Affected component:
- `extensions/googlechat/src/monitor.ts`&lt;/p&gt;
&lt;p&gt;The `allowFrom` checks accept:
- Immutable sender id (`users/&amp;lt;id&amp;gt;`)
- Raw email (`alice@example.com`) for usability&lt;/p&gt;
&lt;p&gt;Historically, `users/&amp;lt;email&amp;gt;` 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.&lt;/p&gt;
&lt;p&gt;### Security Triage (2026-02-14)
Severity: **Low**&lt;/p&gt;
&lt;p&gt;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/&amp;lt;id&amp;gt;`.
- With that level of access, the attacker typically has broader compromise paths.&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;### Remediation / Behavior Changes
