CVE-2024-0618

Name of the Vulnerable Software and Affected Versions The Contact Form Plugin – Fastest Contact Form Builder Plugin for WordPress by Fluent Forms plugin for WordPress versions up to, and including, 5.1.5

Description The issue is related to Stored Cross-Site Scripting via imported form titles due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level access to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The issue only affects multi-site installations and installations where unfiltered html has been disabled.

Recommendations For versions up to, and including, 5.1.5, update to a version later than 5.1.5 to resolve the issue. As a temporary workaround, consider restricting access to imported form titles to minimize the risk of exploitation. Additionally, ensure that unfiltered html is enabled, if possible, to reduce the attack surface.
