CVE-2026-53855

OpenClaw before 2026.4.2 contains an inline-eval bypass vulnerability allowing authenticated operators to weaken strict allowlist checks via shell positional parameters. Attackers can combine allowlisted tools with shell positional arguments to place inline-eval content in shell carriers outside intended allowlist rules, enabling execution of unapproved shell-provided content.

Summary		(es) OpenClaw anterior a 2026.4.2 contiene una vulnerabilidad de omisión de evaluación en línea que permite a operadores autenticados debilitar las estrictas comprobaciones de la lista de permitidos a través de parámetros posicionales de shell. Los atacantes pueden combinar herramientas de la lista de permitidos con argumentos posicionales de shell para colocar contenido de evaluación en línea en portadores de shell fuera de las reglas de la lista de permitidos previstas, lo que permite la ejecución de contenido proporcionado por el shell no aprobado.
