Affected: OpenClaw

OpenClaw before 2026.3.22 contains an improper authentication verification vulnerability in Google Chat app-url webhook handling that accepts add-on principals outside intended deployment bindings. Attackers can bypass webhook authentication by providing non-deployment add-on principals to execute unauthorized actions through the Google Chat integration.
