This is due to missing server-side authentication and the absence of a class allowlist on deserialization, with the only guard being a nonce publicly emitted on any page carrying the [wsdesk_support] shortcode. This makes it possible for unauthenticated attackers to execute code on the server. A successful exploit requires a single anonymous GET to any public page carrying the [wsdesk_support] shortcode to harvest the publicly emitted wsdesk_nonce value, after which a single unauthenticated POST completes the attack.","published":"2026-11-13T10:17:26.483","modified":"2026-11-13T10:17:26.613","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-ajax-functions-two.php#L156"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-ajax-functions-two.php#L265"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-ajax-functions.php#L946"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-init-handler.php#L529"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-public-functions.php#L627"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-public-functions.php#L822"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/vendor/guzzlehttp/guzzle/src/Cookie/FileCookieJar.php#L45"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3797458/elex-helpdesk-customer-support-ticket-system/trunk/includes/class-crm-public-functions.php"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f14b07ce-8893-4f8c-a501-5da6ec5a3b8f?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-13T10:17:26.613"}}
