PolicyController is a utility used to enforce supply chain policy in Kubernetes clusters. In versions prior to 0.2.1 PolicyController will report a false positive, resulting in an admission when it should not be admitted when there is at least one attestation with a valid signature and there are NO attestations of the type being verified (–type defaults to custom). An example image that can be used to test this is ghcr.io/distroless/static@sha256:dd7614b5a12bc4d617b223c588b4e0c833402b8f4991fb5702ea83afad1986e2. Users should upgrade to version 0.2.1 to resolve this issue. There are no workarounds for users unable to upgrade.
The product does not verify, or incorrectly verifies, the cryptographic signature for data.
