CVE-2026-116537

Link Library <= 7.10.0 - Unauthenticated Stored Cross-Site Scripting via 'link_description' Parameter

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.

Link Library <= 7.9.2 - Unauthenticated SQL Injection via 'link_url' Parameter

The Link Library plugin for WordPress is vulnerable to time-based SQL Injection via the 'link_url' parameter in all versions up to, and including, 7.9.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Link Library <= 7.9.4 - Unauthenticated Arbitrary File Deletion via link_url Parameter

The Link Library plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the ll_delete_link_fields function in all versions up to, and including, 7.9.4 This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Exploitation requires the administrator to have enabled the 'Delete local file on link deletion' plugin option (disabled by default) and to subsequently permanently delete the attacker-submitted link, which is a routine moderation action.
