Summary
OpenClaw: Agent hook events could enqueue trusted system events from unsanitized external input
Details

Summary

Agent hook events could enqueue trusted system events from unsanitized external input.

Affected Packages / Versions

  • Package: openclaw
  • Ecosystem: npm
  • Affected versions: < 2026.4.10
  • Patched versions: >= 2026.4.10

Impact

Agent hook dispatch could turn externally supplied hook metadata into trusted system events, allowing untrusted input to enter the agent as higher-trust context.

Technical Details

The fix sanitizes hook names and marks agent hook system events as untrusted before enqueueing them.

Fix

The issue was fixed in #64372. The first stable tag containing the fix is v2026.4.10, and openclaw@2026.4.14 includes the fix.

Fix Commit(s)

  • e3a845bde5b54f4f1e742d0a51ba9860f9619b29
  • PR: #64372

Release Process Note

Users should upgrade to openclaw 2026.4.10 or newer. The latest npm release, 2026.4.14, already includes the fix.
