CVE-2026-80513 — wpForo Forum < 3.1.6 - Subscriber+ PHP Object Injection via Profile Fields

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.
