Detailsinfo

A vulnerability, which was classified as critical, has been found in wpForo Forum Plugin up to 2.4.8/5.x on WordPress. Affected by this issue is the function get_members. The manipulation of the argument row_count with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at wordfence.com. This vulnerability is handled as CVE-2025-4203. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 10/27/2025). This vulnerability is assigned to T1505 by the MITRE ATT&CK project.
