The wpForo Forum WordPress plugin before 3.1.6 does not restrict which classes may be instantiated when it deserializes a user-supplied profile field value, allowing authenticated users with Subscriber-level access and above to inject a PHP Object. No POP chain is present in the wpForo Forum WordPress plugin before 3.1.6 itself; if one is present via another installed wpForo Forum WordPress plugin before 3.1.6 or , this could lead to remote code execution, arbitrary file operations, or SQL injection. This is an incomplete fix of CVE-2026-49769.
