The AJAX handler verifies a nonce but does not check user capabilities. This makes it possible for authenticated attackers with Subscriber-level access and above to modify plugin settings and inject malicious scripts that execute when administrators access the plugin settings page or when any user visits the frontend.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/addons-for-visual-composer/tags/3.9.4/admin/admin-ajax.php#L64","https://plugins.trac.wordpress.org/browser/addons-for-visual-composer/tags/3.9.4/admin/views/settings.php#L568","https://plugins.trac.wordpress.org/browser/addons-for-visual-composer/tags/3.9.4/includes/helper-functions.php#L256","https://www.wordfence.com/threat-intel/vulnerabilities/id/ff0d4000-020b-4e22-9362-a8f0f5df321e?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-3895","score":0.00223,"percentile":0.12941,"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).
