Description

WordPress Plugin Essential Blocks Pro is prone to multiple vulnerabilities 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 these issues to execute arbitrary PHP code within the context of the affected webserver process. WordPress Plugin Essential Blocks Pro version 1.1.0 is vulnerable; prior versions may also be affected.

Remediation

Update to plugin version 1.1.1 or latest
