Description
WordPress Plugin Post Pay Counter is prone to a vulnerability that lets remote attackers inject and execute arbitrary code because the application fails to sanitize user-supplied input before being passed to the unserialize() PHP function. Attackers can possibly exploit this issue to execute arbitrary PHP code within the context of the affected webserver process. WordPress Plugin Post Pay Counter version 2.730 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 2.731 or latest
