What is CVE-2025-4203?

CVE-2025-4203 is a high-severity SQL injection vulnerability in tomdever wpForo Forum, published on 25 Oct 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

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.
