What is CVE-2026-45002?

OpenClaw version prior to 2026.4.20 is vulnerable to a hook session-key bypass, which enables attackers to evade the hooks.allowRequestSessionKey opt-in restriction. This vulnerability arises from the ability to render session keys influenced by external factors through templated hook mappings, effectively compromising webhook routing isolation controls. Users are advised to upgrade to the latest version to mitigate this security risk.
