      "value": "oras-go is a Go library for managing OCI artifacts. Prior to 2.6.1, registry/remote/repository.go in blobStore.completePushAfterInitialPost follows a registry-controlled Location header during monolithic blob upload and reuses the Authorization header from the initial POST request for the subsequent PUT request, allowing a malicious registry to return a cross-host Location and receive the caller's credentials at an attacker-controlled endpoint. This issue is fixed in version 2.6.1."

Antes de la versión 2.6.1, registry/remote/repository.go en blobStore.completePushAfterInitialPost sigue un encabezado Location controlado por el registro durante la carga monolítica de blobs y reutiliza el encabezado Authorization de la solicitud POST inicial para la solicitud PUT subsiguiente, permitiendo que un registro malicioso devuelva una Location entre hosts y reciba las credenciales del llamante en un punto final controlado por el atacante. Este problema está solucionado en la versión 2.6.1."
