      "value": "In Eclipse BaSyx Go Components versions up to and including 1.0.0, ABAC-enabled deployments are vulnerable to an authorization bypass caused by inconsistent trailing-slash handling between the ABAC middleware and the HTTP router.\n\n\n\nThe shared router configuration used Chi's `middleware.StripSlashes`, so a request such as `GET /shells/` was dispatched to the registered `GET /shells` route. However, the ABAC middleware evaluated the original request path including the trailing slash. If ABAC route lookup did not find a matching slash-suffixed route, the request was passed onward and the router then stripped the slash and executed the protected handler without the intended ABAC authorization decision and without the expected ABAC query filters.\n\n\n\nAn unauthenticated or unauthorized network attacker could append a trailing slash to protected API routes to reach handlers that should have been denied by ABAC policy. Depending on the exposed component, HTTP method, and deployed policy, this could allow unauthorized read, create, update, delete, or upload operations.\n\n\n\nThe issue affects ABAC-enabled deployments of services that use the shared router and ABAC middleware, including AAS Repository, Submodel Repository, AAS Registry, Submodel Registry, Concept Description Repository, Discovery, AAS Environment upload, and related services. The issue is fixed in Eclipse BaSyx Go Components v1.0.1."

      "value": "En las versiones de Eclipse BaSyx Go Components hasta la 1.0.0 inclusive, las implementaciones con ABAC habilitado son vulnerables a un bypass de autorización causado por un manejo inconsistente de barras finales entre el middleware ABAC y el router HTTP.\n\nLa configuración compartida del router utilizaba “middleware.StripSlashes” de Chi, por lo que una solicitud como “GET /shells/” se despachaba a la ruta registrada “GET /shells”. Sin embargo, el middleware ABAC evaluaba la ruta de solicitud original incluyendo la barra final. Si la búsqueda de ruta de ABAC no encontraba una ruta coincidente con sufijo de barra, la solicitud se pasaba adelante y el router entonces eliminaba la barra y ejecutaba el gestor protegido sin la decisión de autorización ABAC prevista y sin los filtros de consulta ABAC esperados.\n\nUn atacante de red no autenticado o no autorizado podría añadir una barra final a rutas API protegidas para alcanzar gestores que deberían haber sido denegados por la política ABAC. Dependiendo del componente expuesto, el método HTTP y la política desplegada, esto podría permitir operaciones no autorizadas de lectura, creación, actualización, eliminación o carga.\n\nEl problema afecta a las implementaciones con ABAC habilitado de servicios que utilizan el router compartido y el middleware ABAC, incluyendo AAS Repository, Submodel Repository, AAS Registry, Submodel Registry, Concept Description Repository, Discovery, carga de entorno AAS y servicios relacionados. El problema está solucionado en Eclipse BaSyx Go Components v1.0.1."
