Technical details
A SQL injection vulnerability exists in the wpForo Forum plugin for WordPress (versions <= 3.0.4) due to improper neutralization of special elements used in SQL commands (CWE-89). The flaw is accessible to unauthenticated remote attackers over the network, requiring no user interaction. By sending specially crafted requests, an attacker can execute arbitrary SQL queries against the backend database. This can result in the extraction of sensitive data, such as user credentials and configuration details, or cause limited service disruption. The issue is resolved in version 3.0.5.
