      "value": "OpenClaude is an open-source coding-agent command line interface for cloud and local model providers. Versions prior to 0.5.1 have a logic flaw in `bashToolHasPermission()` inside `src/tools/BashTool/bashPermissions.ts`. When the sandbox auto-allow feature is active and no explicit deny rule is configured, the function returns an `allow` result immediately — before the path constraint filter (`checkPathConstraints`) is ever evaluated. This allows commands containing path traversal sequences (e.g., `../../../../../etc/passwd`) to bypass directory restrictions entirely. Version 0.5.1 contains a patch for the issue."

      "value": "OpenClaude es una interfaz de línea de comandos de agente de codificación de código abierto para proveedores de modelos locales y en la nube. Las versiones anteriores a la 0.5.1 tienen un fallo lógico en “bashToolHasPermission()” dentro de “src/tools/BashTool/bashPermissions.ts”. Cuando la función de auto-permiso del sandbox está activa y no hay una regla de denegación explícita configurada, la función devuelve un resultado de “allow” inmediatamente - antes de que el filtro de restricción de ruta (“checkPathConstraints”) sea evaluado. Esto permite que los comandos que contienen secuencias de salto de ruta (por ejemplo, “.. / .. / .. / .. / .. / etc/p4ssd”) eludan por completo las restricciones de directorio. La versión 0.5.1 contiene un parche para el problema."
