medium 4.4 CVE-2026-1191 · published 2026-01-24

Stored cross-site scripting (XSS) in JavaScript Notifier (1.2.8 and older)

Affected: 1.2.8 and older
Fixed in: unknown
Access needed (per CVSS): Needs an admin-level account
Range from: CVE record (the advisory publisher) · score by Wordfence

Details from the advisory

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.
