Upgrade zotregistry.dev/zot/pkg/api/ to version 2.1.0 or higher.
Overview
Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key due to the GetBlob() function. An attacker can read images that the accessControl policy denies if they have read access to any other second repository.
Notes:
This attack only allows accessing blobs, both config and layers, by digest. Manifests are not included.
This attack requires the attacker to know the name of a private image and its layer digests.
Workaround
The attack may be mitigated by configuring dedupe: false in the "storage" settings. dedupe is enabled by default using the BoltDB cache driver.
