{"cve":"CVE-2026-4326","nvd":{"published":"2026-04-09T02:16:16.530","modified":"2026-07-24T20:10:00.147","status":"Deferred","description":"The Vertex Addons for Elementor plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.6.4. This is due to improper authorization enforcement in the activate_required_plugins() function. Specifically, the current_user_can('install_plugins') capability check does not terminate execution when it fails — it only sets an error message variable while allowing the plugin installation and activation code to execute. The error response is only sent after the installation and activation have already completed. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install and activate arbitrary plugins from the WordPress.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/addons-for-elementor-builder/tags/1.6.4/app/Ajax.php#L229","https://plugins.trac.wordpress.org/browser/addons-for-elementor-builder/tags/1.6.4/app/Ajax.php#L232","https://plugins.trac.wordpress.org/browser/addons-for-elementor-builder/tags/1.6.4/app/Ajax.php#L264","https://plugins.trac.wordpress.org/browser/addons-for-elementor-builder/tags/1.6.4/app/Ajax.php#L278","https://plugins.trac.wordpress.org/browser/addons-for-elementor-builder/trunk/app/Ajax.php#L229"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-4326","score":0.00578,"percentile":0.47608,"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).
