CVE-2026-29613Network attack vector

Unauthenticated event injection via loopback trust

Published Mar 5, 2026 · Updated Mar 5, 2026

Authentication bypass in OpenClaw before 2026.2.12 allows remote attackers to inject BlueBubbles message and reaction events. The BlueBubbles webhook monitor accepts a request as authenticated when req.socket.remoteAddress is loopback, without requiring the configured secret or checking forwarding headers. Exposure requires the optional plugin and a reverse proxy that connects over loopback, so the attacker must reach the proxied webhook endpoint.
