{"cve":"CVE-2026-6439","nvd":{"published":"2026-04-17T09:16:05.447","modified":"2026-06-17T11:00:49.580","status":"Deferred","description":"The VideoZen plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 1.0.1. This is due to insufficient input sanitization and output escaping in the videozen_conf() function. The 'lang' POST parameter is stored directly via update_option() without any sanitization, and later echoed inside a <textarea> element without applying esc_textarea() or any equivalent escaping function. This makes it possible for authenticated attackers with Administrator-level access and above to inject arbitrary web scripts into the plugin settings page that will execute whenever any user accesses that page.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","score":4.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/videozen/tags/1.0.1/videozen-conf.php#L24","https://plugins.trac.wordpress.org/browser/videozen/tags/1.0.1/videozen-conf.php#L69","https://plugins.trac.wordpress.org/browser/videozen/trunk/videozen-conf.php#L24","https://plugins.trac.wordpress.org/browser/videozen/trunk/videozen-conf.php#L69","https://www.wordfence.com/threat-intel/vulnerabilities/id/47bcd04b-a479-49f2-94d0-df2a7684210c?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-6439","score":0.00199,"percentile":0.09777,"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).
