Affected packages
• Go github.com/sigstore/policy-controller: < 0.2.1 → fixed in 0.2.1
Description
PolicyController will report a false positive, resulting in an admission when it should not be admitted when:

• There are NO attestations of the type being verified (--type defaults to "custom")
Users should upgrade to cosign version 0.2.1 or greater for a patch. There are no known workarounds at this time.
