The Link Library plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'link_description' parameter in all versions up to, and including, 7.10.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This exploit requires the site administrator to have enabled the non-default 'Convert [] to <> in Link Description and Notes' (use_html_tags) setting; when this option is off, the bracket-to-angle-bracket conversion never runs and the payload is never reconstructed into executable HTML.
