Name of the Vulnerable Software and Affected Versions Related Posts Lite plugin for WordPress versions up to and including 1.12

Description The Related Posts Lite plugin for WordPress is susceptible to Stored Cross-Site Scripting through admin settings. Insufficient input sanitization and output escaping allows authenticated attackers with administrator-level permissions and above 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 Related Posts Lite plugin to a version later than 1.12.
