Name of the Vulnerable Software and Affected Versions:

WP Easy Contact versions up to and including 4.0.1

Description:

The WP Easy Contact plugin for WordPress is susceptible to stored cross-site scripting through the `noaccess msg` parameter. Insufficient input sanitization and output escaping allow authenticated attackers with Contributor-level access or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses an injected page.

Recommendations:

Update WP Easy Contact to a version later than 4.0.1.
