WordPress Plugin wpcu3er is prone to a vulnerability that lets attackers upload arbitrary files 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 webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible. WordPress Plugin wpcu3er version 0.55 is vulnerable; prior versions may also be affected.


Update to plugin version 0.56 or latest
