Affected packages

• npm openclaw: < 2026.4.20 → fixed in 2026.4.20

Description

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`.
