DescriptionCVE.org

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.

AnalysisAI

Stored cross-site scripting in the JavaScript Notifier WordPress plugin through version 1.2.8 allows administrators to inject malicious scripts into website pages due to improper input sanitization in plugin settings. When users visit affected pages, the injected scripts execute in their browsers, potentially compromising user sessions or stealing sensitive data. This requires administrator-level access to exploit but affects all website visitors who view the compromised pages.
