CVE-2026-32896

medium

Description

The BlueBubbles webhook handler in OpenClaw versions prior to 2026.2.21 contains a passwordless fallback authentication path that allows unauthenticated webhook events in certain reverse-proxy or local routing configurations. Attackers can bypass webhook authentication by exploiting the loopback/proxy heuristics to send unauthenticated webhook events to the BlueBubbles plugin.
