Description

WordPress Plugin MailPoet Newsletters (Previous) is prone to a vulnerability that lets attackers upload arbitrary files because the application fails to properly sanitize 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 MailPoet Newsletters (Previous) version 2.6.7 is vulnerable; prior versions may also be affected.
