CVE-2026-0910Network attack vector

Authenticated PHP object injection via unsafe deserialization

Published Feb 11, 2026 · Updated Feb 11, 2026

PHP object injection in gVectors Team wpForo Forum 2.4.13 and earlier allows remote authenticated users to inject PHP objects via serialized data. The wpforo_display_array_data function deserializes untrusted input and constructs PHP objects from attacker-controlled serialized values. Subscriber-level access reaches the flaw, but file deletion, data access, or code execution requires a compatible POP chain from another installed plugin or theme.
