Technical details
The vulnerability is a SQL injection flaw in the WP w3all phpBB plugin that can be exploited by authenticated users with subscriber-level permissions. The root cause involves insufficient input validation in database queries. An attacker with subscriber access can inject malicious SQL code to read, modify, or delete arbitrary database records. The vulnerability is not network-unauthenticated; it requires a valid WordPress subscriber account. The vendor released a patched version 3.0.6 that addresses the injection flaw.
