Overview
Affected versions of this package are vulnerable to Improper Authentication due to the use of the search API to fetch entries that apply to a signature being verified. An attacker can manipulate the verification process by ensuring that the search parameters match either the public key or the payload.
Note: This can lead to the selection of an incorrect Rekor entry, which might not match the payload being verified, thus allowing the verification to pass incorrectly.
