{"id":"CVE-2026-4002","state":"PUBLISHED","title":"Petje.af <= 2.1.8 - Cross-Site Request Forgery to Account Deletion via 'petjeaf_disconnect' AJAX Action","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.","publishedAt":"2026-04-15T08:28:14.102Z","updatedAt":"2026-04-15T15:50:38.937Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["petjeaf Petje.af"],"affected":[{"vendor":"petjeaf","product":"Petje.af","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.1.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/28a071ac-37ee-4fb9-b8c6-0a782ee673b4?source=cve","https://plugins.trac.wordpress.org/browser/petje-af/trunk/includes/class-petje-af-oauth2-provider.php#L346","https://plugins.trac.wordpress.org/browser/petje-af/tags/2.1.8/includes/class-petje-af-oauth2-provider.php#L346","https://plugins.trac.wordpress.org/browser/petje-af/trunk/includes/class-petje-af-oauth2-provider.php#L326","https://plugins.trac.wordpress.org/browser/petje-af/tags/2.1.8/includes/class-petje-af-oauth2-provider.php#L326","https://plugins.trac.wordpress.org/browser/petje-af/trunk/includes/class-petje-af.php#L182","https://plugins.trac.wordpress.org/browser/petje-af/tags/2.1.8/includes/class-petje-af.php#L182"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4002.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4002","state":"PUBLISHED","datePublished":"2026-04-15T08:28:14.102Z","dateUpdated":"2026-04-15T15:50:38.937Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-11T18:44:40.867Z"},"containers":{"cna":{"title":"Petje.af <= 2.1.8 - Cross-Site Request Forgery to Account Deletion via 'petjeaf_disconnect' AJAX Action","descriptions":[{"lang":"en","value":"The Petje.af plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 2.1.8.
