  2. Vulnerabilities (CVE)
  3. CVE-2026-32896
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.

Summary
  • (es) Las versiones de OpenClaw anteriores a 2026.2.21 BlueBubbles webhook gestor contienen una ruta de autenticación de respaldo sin contraseña que permite eventos de webhook no autenticados en ciertas configuraciones de proxy inverso o de enrutamiento local. Los atacantes pueden eludir la autenticación de webhook al explotar la heurística de bucle invertido/proxy para enviar eventos de webhook no autenticados al plugin de BlueBubbles.
