CVE-2026-45002: OpenClaw: Hook mapping templates could bypass hook session-key opt-in
Affected Packages / Versions - Package: openclaw (npm) - Affected versions: < 2026.4.20 - Patched version: 2026.4.20 Impact Templated hook mapping sessionKey values were treated differently from request-supplied session keys. A hook mapping could render an externally influenced session key even when hooks.allowRequestSessionKey was disabled, bypassing the intended routing opt-in for hook callers.

Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
< 2026.4.20 - Patched version:
2026.4.20
Impact
Templated hook mapping sessionKey values were treated differently from request-supplied session keys. A hook mapping could render an externally influenced session key even when hooks.allowRequestSessionKey was disabled, bypassing the intended routing opt-in for hook callers.
This affects webhook routing isolation. It does not grant host execution by itself. Severity is medium.
Fix
Template-rendered mapping session keys are now treated as externally supplied routing input and require hooks.allowRequestSessionKey=true plus the existing prefix policy checks.
Fix commit:

Release
Fixed in OpenClaw 2026.4.20.
