Description
WordPress Plugin WP Forum Server is prone to an SQL injection vulnerability because the application fails to properly sanitize user-supplied input before using it in an SQL query. A successful exploit will allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database. WordPress Plugin WP Forum Server version 1.7 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 1.7.1 or latest
