The wpForo Forum plugin for WordPress is vulnerable to error‐based or time-based SQL Injection via the get_members() function in all versions up to, and including, 2.4.8 due to missing integer validation on the 'offset' and 'row_count' parameters. The function blindly interpolates 'row_count' into a 'LIMIT offset,row_count' clause using esc_sql() rather than enforcing numeric values. MySQL 5.x’s grammar allows a 'PROCEDURE ANALYSE' clause immediately after a LIMIT clause. Unauthenticated attackers controlling 'row_count' can append a stored‐procedure call, enabling error‐based or time‐based blind SQL injection that can be used to extract sensitive information from the database.
