Name of the Vulnerable Software and Affected Versions Tune Library plugin for WordPress versions up to and including 1.6.3

Description The Tune Library plugin for WordPress is susceptible to Stored Cross-Site Scripting through the CSV import functionality. This is a result of inadequate input sanitization and output escaping of user-provided attributes. Authenticated attackers with Subscriber-level access or higher can inject arbitrary web scripts into pages. These scripts will execute when a user accesses the affected page. The CSV import functionality lacks authorization checks and does not sanitize imported data before rendering it through the [tune-library] shortcode.

Recommendations Update the Tune Library plugin to a version later than 1.6.3.
