{"cve":"CVE-2026-4002","nvd":{"published":"2026-04-15T09:16:32.547","modified":"2026-06-17T10:55:50.127","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-352"],"references":["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/tags/2.1.8/includes/class-petje-af-oauth2-provider.php#L346","https://plugins.trac.wordpress.org/browser/petje-af/tags/2.1.8/includes/class-petje-af.php#L182","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/trunk/includes/class-petje-af-oauth2-provider.php#L346"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-4002","score":0.00163,"percentile":0.05521,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
