Description
WordPress Plugin Super Forms-Drag & Drop Form Builder is prone to a vulnerability that lets attackers upload arbitrary files because the application fails to properly verify user-supplied input. An attacker can exploit this vulnerability to upload arbitrary code and run it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible. WordPress Plugin Super Forms-Drag & Drop Form Builder version 4.9.700 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 4.9.703 or latest
