{"id":"CVE-2026-1191","state":"PUBLISHED","title":"JavaScript Notifier <= 1.2.8 - Authenticated (Administrator+) Stored Cross-Site Scripting via Plugin Settings","description":"The JavaScript Notifier plugin for WordPress is vulnerable to Stored Cross-Site Scripting via plugin settings in all versions up to, and including, 1.2.8. This is due to insufficient input sanitization and output escaping on user-supplied attributes in the `wp_footer` action. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-01-24T09:08:07.887Z","updatedAt":"2026-04-08T17:10:25.216Z","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":["freemp JavaScript Notifier"],"affected":[{"vendor":"freemp","product":"JavaScript Notifier","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.2.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/97696702-4d40-41dd-a25f-f2ee7681a2c9?source=cve","https://plugins.trac.wordpress.org/browser/javascript-notifier/trunk/javascript-notifier.php#L75","https://plugins.trac.wordpress.org/browser/javascript-notifier/tags/1.2.8/javascript-notifier.php#L75","https://plugins.trac.wordpress.org/changeset/3449861/"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1191.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1191","state":"PUBLISHED","datePublished":"2026-01-24T09:08:07.887Z","dateUpdated":"2026-04-08T17:10:25.216Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-19T13:45:14.423Z"},"containers":{"cna":{"title":"JavaScript Notifier <= 1.2.8 - Authenticated (Administrator+) Stored Cross-Site Scripting via Plugin Settings","descriptions":[{"lang":"en","value":"The JavaScript Notifier plugin for WordPress is vulnerable to Stored Cross-Site Scripting via plugin settings in all versions up to, and including, 1.2.8.
