Secure Passkeys <= 1.2.1 - Missing Authorization to Authenticated (Subscriber+) Passkey Exposure and Deletion

The Secure Passkeys plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the delete_passkey() and passkeys_list() function in all versions up to, and including, 1.2.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to view and delete passkeys.
