What the vulnerability does
01Description
The List category posts plugin for WordPress is vulnerable to time-based SQL Injection via the ‘starting_with’ parameter of the catlist shortcode in all versions up to, and including, 0.91.0 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 Contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

List category posts versions up to 0.91.0 contain a SQL injection vulnerability in database query construction. An attacker with low-level site access can craft malicious input to read sensitive data from the database, including user information and configuration details.
