Summary

cosign's `cosign verify-attestaton --type` can report a false positive if any attestation exists

Details

cosign verify-attestation used with the --type flag will report a false positive verification when:

There is at least one attestation with a valid signature
There are NO attestations of the type being verified (--type defaults to "custom")

This can happen when signing with a standard keypair and with "keyless" signing with Fulcio. Users should upgrade to cosign version 1.10.1 or greater for a patch. Currently the only workaround is to upgrade.
