AI-suggested

Until an official fix is released, users should consider disabling or removing the vulnerable plugin version or applying manual input sanitization and output escaping if feasible. Additionally, educating users to avoid clicking suspicious links can reduce risk. Monitor vendor channels for updates and apply official patches promptly once available.

Description

The Bounce Handler MailPoet 3 plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'page' parameter in all versions up to, and including, 1.3.21 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
