  • GHSA-2xcp-x87w-q377OpenClaw: Hook mapping templates could bypass hook session-key opt-in2026-04-25ghsa · osvUS

    ## 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`.
