Description
WordPress Plugin MailPoet Newsletters (Previous) is prone to multiple vulnerabilities, including cross-site scripting and SQL injection vulnerabilities because it fails to properly sanitize user-supplied input. An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, to steal cookie-based authentication credentials, to compromise the application, access or modify data or to exploit vulnerabilities in the underlying database. WordPress Plugin MailPoet Newsletters (Previous) version 2.7.2 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 2.7.3 or latest
