This is due to missing nonce validation in the ajax_revoke_token() function which handles the 'petjeaf_disconnect' AJAX action. The function performs destructive operations including revoking OAuth2 tokens, deleting user meta, and deleting WordPress user accounts (for users with the 'petjeaf_member' role) without verifying the request originated from a legitimate source. This makes it possible for unauthenticated attackers to force authenticated users to delete their Petje.af member user accounts via a forged request granted the victim clicks on a link or visits a malicious site."}], "lastModified": "2026-06-17T10:55:50.127", "sourceIdentifier": "security@wordfence.com"}
