Name of the Vulnerable Software and Affected Versions User Language Switch plugin for WordPress versions prior to 1.6.11

Description The User Language Switch plugin for WordPress is susceptible to Stored Cross-Site Scripting through the tab color picker language switch parameter. Insufficient input sanitization and output escaping allow authenticated attackers with administrator-level access or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses the injected page. This issue only impacts multi-site installations and installations where unfiltered html has been disabled.

Recommendations Update the User Language Switch plugin to version 1.6.11 or later.
