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.","epss":{"date":"2026-11-13","percentile":0.71709,"score":0.01337},"exploits":[],"kev":null,"metrics":[{"score":9.8,"severity":"critical","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},{"score":9.8,"severity":"critical","source":"NVD: security@wordfence.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1794611833633,"publishedAt":1794562517360,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f14b07ce-8893-4f8c-a501-5da6ec5a3b8f?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-public-functions.php#L822"},{"source":"CNA: Wordfence","tags":[],"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"},{"source":"CNA: Wordfence","tags":[],"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"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-public-functions.php#L627"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-ajax-functions.php#L946"},{"source":"CNA: Wordfence","tags":[],"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"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-init-handler.php#L529"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3797458/elex-helpdesk-customer-support-ticket-system/trunk/includes/class-crm-public-functions.php"},{"source":"security@wordfence.com","tags":[],"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"},{"source":"security@wordfence.com","tags":[],"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"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-ajax-functions.php#L946"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-init-handler.php#L529"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-public-functions.php#L627"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/elex-helpdesk-customer-support-ticket-system/tags/3.3.8/includes/class-crm-public-functions.php#L822"},{"source":"security@wordfence.com","tags":[],"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"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/changeset/3797458/elex-helpdesk-customer-support-ticket-system/trunk/includes/class-crm-public-functions.php"},{"source":"security@wordfence.com","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f14b07ce-8893-4f8c-a501-5da6ec5a3b8f?source=cve"}],"remediation":[],"revision":"cbd0f3e10a8f671140debcdf077c0c17b2c0e80a1b096cf36563cedb9aaa5635","sources":[{"modifiedAt":1794609019362,"name":"CNA: Wordfence","retrievedAt":1794611304996,"url":"https://www.cve.org/CVERecord?id=CVE-2026-119077"},{"modifiedAt":1794611833633,"name":"NVD","retrievedAt":1794615497616,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-119077"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1794611327555,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-119077"}],"ssvc":{"assessedAt":1794588129202,"automatable":"yes","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"ELEX WordPress HelpDesk & Customer Ticketing System <= 3.3.9 - Unauthenticated PHP Object Injection to Remote Code Execution via 'form' Parameter","updatedAt":1794615497616}
