FKIE_CVE-2026-33068

Vulnerability from fkie_nvd - Published: 2026-03-20 09:16 - Updated: 2026-03-24 15:46
Summary
Claude Code is an agentic coding tool. Versions prior to 2.1.53 resolved the permission mode from settings files, including the repo-controlled .claude/settings.json, before determining whether to display the workspace trust confirmation dialog. A malicious repository could set permissions.defaultMode to bypassPermissions in its committed .claude/settings.json, causing the trust dialog to be silently skipped on first open. This allowed a user to be placed into a permissive mode without seeing the trust confirmation prompt, making it easier for an attacker-controlled repository to gain tool execution without explicit user consent. This issue has been patched in version 2.1.53.

Las versiones anteriores a la 2.1.53 resolv\u00edan el modo de permiso a partir de archivos de configuraci\u00f3n, incluyendo el .claude/settings.json controlado por el repositorio, antes de determinar si mostrar el di\u00e1logo de confirmaci\u00f3n de confianza del espacio de trabajo. Un repositorio malicioso podr\u00eda establecer permissions.defaultMode a bypassPermissions en su .claude/settings.json confirmado, causando que el di\u00e1logo de confianza se omitiera silenciosamente en la primera apertura. Esto permit\u00eda que un usuario fuera colocado en un modo permisivo sin ver la solicitud de confirmaci\u00f3n de confianza, facilitando que un repositorio controlado por un atacante obtuviera la ejecuci\u00f3n de la herramienta sin el consentimiento expl\u00edcito del usuario. Este problema ha sido parcheado en la versi\u00f3n 2.1.53."
