WordPress Plugin WP Email Template PHP Object Injection (2.4.0)
Description
WordPress Plugin WP Email Template 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 delete files that the current user has access to. WordPress Plugin WP Email Template version 2.4.0 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 2.4.1 or latest
