CVE-2026-26316Network attack vector

Unauthenticated event injection via loopback proxy trust

Published Feb 19, 2026 · Updated Feb 19, 2026

Incorrect authorization in OpenClaw before 2026.2.13 allows remote attackers to inject BlueBubbles webhook events through a loopback proxy. The BlueBubbles webhook handler treats a loopback TCP peer as authenticated even when its configured secret is missing or incorrect. Exposure requires the optional plugin and a same-host reverse proxy or SSRF path that reaches the loopback-bound Gateway; injected events enter the agent pipeline.
