Description
WordPress Plugin TDO Mini Forms is prone to a vulnerability that lets attackers upload arbitrary files. The issue occurs because the application fails to adequately sanitize user-supplied input. An attacker can exploit this vulnerability to upload arbitrary PHP code and run it in the context of the Web server process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible. WordPress Plugin TDO Mini Forms version 0.13.9 is vulnerable; prior versions may also be affected.
Remediation
Remove the upload widget from your forms or only allow trusted users to upload files or disable the plugin until a fix is available
