  3. CVE-2026-27670
OpenClaw versions prior to 2026.3.2 contain a race condition vulnerability in ZIP extraction that allows local attackers to write files outside the intended destination directory. Attackers can exploit a time-of-check-time-of-use race between path validation and file write operations by rebinding parent directory symlinks to redirect writes outside the extraction root.

Summary
  • (es) Las versiones de OpenClaw anteriores a la 2026.3.2 contienen una vulnerabilidad de condición de carrera en la extracción de archivos ZIP que permite a atacantes locales escribir archivos fuera del directorio de destino previsto. Los atacantes pueden explotar una condición de carrera de tipo 'tiempo de verificación, tiempo de uso' entre la validación de rutas y las operaciones de escritura de archivos al reasignar enlaces simbólicos de directorios padre para redirigir las escrituras fuera de la raíz de extracción.
