Description

OpenClaw versions prior to 2026.2.14 contain a webhook routing vulnerability in the Google Chat monitor component that allows cross-account policy context misrouting when multiple webhook targets share the same HTTP path. Attackers can exploit first-match request verification semantics to process inbound webhook events under incorrect account contexts, bypassing intended allowlists and session policies.
