Technical details

The Taskbuilder plugin for WordPress is vulnerable to time-based blind SQL injection due to insufficient escaping of the 'project_search' parameter and a lack of SQL query preparation. This vulnerability exists in all versions up to and including 5.0.6. An authenticated attacker with Subscriber-level permissions or higher can exploit this by sending crafted network requests to append malicious SQL commands to existing queries. Successful exploitation allows the attacker to exfiltrate sensitive data from the database based on the time delay of the server's response. A patch appears to be available in the plugin's changeset 3507782.
