OpenClaw: Hook mapping templates could bypass hook session-key opt-in
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
## 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:
- `5275d008ed33203dba3f98e969ad683a65c416c3`
## Release
Fixed in OpenClaw `2026.4.20`.
