CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
published
Mar 26, 2026
The Broken Link Checker plugin for WordPress is vulnerable to SQL Injection in versions up to, and including, 2.4.7 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with editor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Broken Link Checker <= 2.4.4 - Missing Autorization to Authenticated (Subscriber+) Plugin Status Dashboard View
medium
✓ patched
The Broken Link Checker plugin for WordPress is vulnerable to unauthorized data access due to a missing capability check on the ajax_full_status and ajax_dashboard_status functions in all versions up to, and including, 2.4.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to view the plugin's status.
