Petje.af, CVE-2026-4002

CVE, Research URL: CVE-2026-4002
Home page URL: Security reports for Petje.af
Application: Petje.af
Published on: Apr 15, 2026
Research Description: The Petje.af plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 2.1.8. 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.
Affected versions: max 2.1.8.
Status: vulnerable
