CVE-2026-40503

OpenHarness prior to commit dd1d235 contains a path traversal vulnerability that allows remote gateway users with chat access to read arbitrary files by supplying path traversal sequences to the /memory show slash command. Attackers can manipulate the path input parameter to escape the project memory directory and access sensitive files accessible to the OpenHarness process without filesystem containment validation.

Summary		(es) OpenHarness antes del commit dd1d235 contiene una vulnerabilidad de salto de ruta que permite a usuarios remotos de la pasarela con acceso al chat leer archivos arbitrarios al proporcionar secuencias de salto de ruta al comando de barra /memory show. Los atacantes pueden manipular el parámetro de entrada de ruta para escapar del directorio de memoria del proyecto y acceder a archivos sensibles accesibles para el proceso de OpenHarness sin validación de contención del sistema de archivos.
