WordPress Plugin Users Ultra Membership 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 Users Ultra Membership version 1.5.58 is vulnerable; prior versions may also be affected.


Update to plugin version 1.5.59 or latest
