## Overview

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
 * 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.

## Affected packages

- `github.com/sigstore/policy-controller < 0.2.1`

## Remediation

Upgrade to a patched release:

- `github.com/sigstore/policy-controller 0.2.1`
