What is CVE-2026-26316?

CVE-2026-26316 is a high-severity authentication bypass vulnerability in Openclaw Openclaw, published on 19 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

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.

Weakness: CWE-863
