Prior to 2.1.0, the cache driver `GetBlob()` allows read access to any blob without access control check. If a Zot `accessControl` policy allows users read access to some repositories but restricts read access to other repositories and `dedupe` is enabled (it is enabled by default), then an attacker who knows the name of an image and the digest of a blob (that they do not have read access to), they may maliciously read it via a second repository they do have read access to. \n This attack is possible because [`ImageStore.CheckBlob()` calls `checkCacheBlob()`](https://github.com/project-zot/zot/blob/v2.1.0-rc2/pkg/storage/imagestore/imagestore.go#L1158-L1159) to find the blob a global cache by searching for the digest. If it is found, it is copied to the user requested repository with `copyBlob()`. The attack may be mitigated by configuring \"dedupe\": false in the \"storage\" settings. The vulnerability is fixed in 2.1.0."},{"lang":"es","value":"zot es un registro de imágenes OCI. Antes de 2.1.0, el controlador de caché `GetBlob()` permite acceso de lectura a cualquier blob sin verificación de control de acceso. Si una política `accessControl` de Zot permite a los usuarios acceso de lectura a algunos repositorios pero restringe el acceso de lectura a otros repositorios y `dedupe` está habilitado (está habilitado de forma predeterminada), entonces un atacante que conoce el nombre de una imagen y el resumen de una blob (al que no tienen acceso de lectura), pueden leerlo maliciosamente a través de un segundo repositorio al que sí tienen acceso de lectura. Este ataque es posible porque [`ImageStore.CheckBlob()` llama a `checkCacheBlob()`](https://github.com/project-zot/zot/blob/v2.1.0-rc2/pkg/storage/imagestore/imagestore .go#L1158-L1159) para encontrar el blob como caché global buscando el resumen.
