Summary

The Related Posts Lite plugin for WordPress up to version 1.12 is vulnerable to Stored Cross-Site Scripting via admin settings. Insufficient input sanitization and output escaping allow authenticated attackers with administrator-level permissions or higher to inject arbitrary web scripts that execute when a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Risk Assessment

An administrator can inject malicious scripts that execute for other users, potentially leading to session hijacking or malware distribution.

Recommendation

Update the Related Posts Lite plugin to the latest patched version. Restrict administrator privileges and enable unfiltered_html only for trusted users.
