CVE-2025-54795

Claude Code is an agentic coding tool. In versions below 1.0.20, an error in command parsing makes it possible to bypass the Claude Code confirmation prompt to trigger execution of an untrusted command. Reliably exploiting this requires the ability to add untrusted content into a Claude Code context window. This is fixed in version 1.0.20.

Summary		(es) Claude Code es una herramienta de codificación agentica. En versiones anteriores a la 1.0.20, un error en el análisis de comandos permite omitir la solicitud de confirmación de Claude Code para activar la ejecución de un comando no confiable. Para aprovechar esto de forma fiable, es necesario poder añadir contenido no confiable a una ventana de contexto de Claude Code. Esto se ha corregido en la versión 1.0.20.
