Name of the Vulnerable Software and Affected Versions The Ultimate Addons for Contact Form 7 WordPress plugin versions prior to 3.1.29

Description The issue concerns the Ultimate Addons for Contact Form 7 WordPress plugin, where some settings are not properly sanitized and escaped. This could allow high-privilege users, such as administrators, to perform Stored Cross-Site Scripting attacks, even when the unfiltered html capability is disallowed, for example, in a multisite setup.

Recommendations For versions prior to 3.1.29, update to version 3.1.29 or later to resolve the issue. As a temporary workaround, consider restricting the use of the plugin's settings to minimize the risk of exploitation. Additionally, ensure that the unfiltered html capability is properly configured and disallowed for non-admin users to reduce the attack surface.
