Name of the Vulnerable Software and Affected Versions JavaScript Notifier plugin for WordPress versions up to and including 1.2.8

Description The JavaScript Notifier plugin for WordPress is susceptible to Stored Cross-Site Scripting through plugin settings. This is caused by inadequate input sanitization and output escaping of user-supplied attributes within the wp footer action. An authenticated attacker with administrator privileges can inject arbitrary web scripts into pages, which will then execute when a user accesses the affected page.

Recommendations Update the JavaScript Notifier plugin to a version newer than 1.2.8.
