Auth bypass in Openclaw
CVE-2026-26316
OpenClaw is a personal AI assistant. Prior to 2026.2.13, the optional BlueBubbles iMessage channel plugin could accept webhook requests as authenticated based only on the TCP peer address being loopback (`127.0.0.1`, `::1`, `::ffff:127.0.0.1`) even when the configured webhook secret was missing or incorrect. This does not affect the default iMessage integration unless BlueBubbles is installed and enabled. Version 2026.2.13 contains a patch. Other mitigations include setting a non-empty BlueBubbles webhook password and avoiding deployments where a public-facing reverse proxy forwards to a loopback-bound Gateway without strong upstream authentication.
