CVE-2024-12261

Name of the Vulnerable Software and Affected Versions SmartEmailing.cz plugin for WordPress versions prior to 2.2.1

Description The issue arises from insufficient input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts in pages via the se-lists-updated parameter. This enables attackers to execute scripts if they can trick a user into performing an action, such as clicking on a link.

Recommendations For versions up to and including 2.2.0, update to a version later than 2.2.0 to resolve the issue. As a temporary workaround, consider restricting access to the se-lists-updated parameter to minimize the risk of exploitation.
