Unauthenticated object injection via widget AJAX handlers
Published Jun 15, 2026 · Updated Jun 15, 2026
PHP object injection in gVectors Team wpForo Forum 3.1.0 and earlier allows remote attackers to inject objects through widget AJAX requests. The unauthenticated widget AJAX handlers deserialize attacker-controlled PHP object data, but the vendor has not disclosed the endpoint, parameter, or function performing the operation. Exploitation requires no account or user interaction; code execution or other impact depends on a usable POP chain in the WordPress environment.
