Description

notation is a CLI tool to sign and verify OCI artifacts and container images. An attacker who has compromised a registry can cause users to verify the wrong artifact. The problem has been fixed in the release v1.0.0-rc.6. Users should upgrade their notation-go library to v1.0.0-rc.6 or above. Users unable to upgrade may restrict container registries to a set of secure and trusted container registries.
