{"id":"CVE-2026-6439","state":"PUBLISHED","title":"VideoZen <= 1.0.1 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'VideoZen available subtitles languages' Field","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.","publishedAt":"2026-04-17T08:28:26.200Z","updatedAt":"2026-04-20T14:59:14.759Z","severity":{"score":4.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["jconti VideoZen"],"affected":[{"vendor":"jconti","product":"VideoZen","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/47bcd04b-a479-49f2-94d0-df2a7684210c?source=cve","https://plugins.trac.wordpress.org/browser/videozen/trunk/videozen-conf.php#L69","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/tags/1.0.1/videozen-conf.php#L24"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6439.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6439","state":"PUBLISHED","datePublished":"2026-04-17T08:28:26.200Z","dateUpdated":"2026-04-20T14:59:14.759Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-16T18:09:59.771Z"},"containers":{"cna":{"title":"VideoZen <= 1.0.1 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'VideoZen available subtitles languages' Field","descriptions":[{"lang":"en","value":"The VideoZen plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 1.0.1.
