CVE-2023-6842

Summary

CVE-2023-6842 is a stored Cross-Site Scripting (XSS) vulnerability affecting the Formidable Forms plugin for WordPress. The issue lies in the name field label and description field label parameters, which lack sufficient input sanitization and output escaping. This allows authenticated attackers, even those with lower user levels if granted proper permissions, to inject malicious web scripts. The scripts execute whenever a user accesses an affected page, potentially leading to data theft, unauthorized account access, or site defacement. This vulnerability primarily affects multi-site installations and those with unfiltered_html disabled, but administrators can extend permissions to other user types, increasing the risk.
