CVE-2026-27523

Estado: AnalizadaMedia (6.9)—

OpenClaw versions prior to 2026.2.24 contain a sandbox bind validation vulnerability allowing attackers to bypass allowed-root and blocked-path checks via symlinked parent directories with non-existent leaf paths. Attackers can craft bind source paths that appear within allowed roots but resolve outside sandbox boundaries once missing leaf components are created, weakening bind-source isolation enforcement.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

Los atacantes pueden crear rutas de origen de enlace (bind source paths) que parecen estar dentro de raíces permitidas pero se resuelven fuera de los límites del sandbox una vez que se crean los componentes hoja (leaf components) que faltan, debilitando la aplicación del aislamiento de origen de enlace (bind-source isolation enforcement)."
