Name of the Vulnerable Software and Affected Versions: Ultra Addons for Contact Form 7 versions up to, and including, 3.5.21

Description: The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping on user-supplied attributes in the plugin's UACF7 CUSTOM FIELDS shortcode. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations: For versions up to, and including, 3.5.21, update to a version that addresses the insufficient input sanitization and output escaping issue in the UACF7 CUSTOM FIELDS shortcode. As a temporary workaround, consider restricting access to the UACF7 CUSTOM FIELDS shortcode for users with contributor-level access and above until a patch is available.
