What is CVE-2026-15090?

The Link Library plugin for WordPress contains a vulnerability that allows for time-based SQL Injection through the 'link_url' parameter. This occurs due to inadequate escaping of user-supplied input and poor preparation in the SQL queries executed by the plugin. Attackers who are not authenticated can exploit this weakness to inject additional SQL commands into existing queries, potentially gaining access to sensitive data stored within the database. It is crucial for users of affected versions to update their plugins to safeguard against this type of attack.
