Name of the Vulnerable Software and Affected Versions: The Ultimate TinyMCE plugin for WordPress versions up to, and including, 5.7

Description: The issue is related to Stored Cross-Site Scripting via the 'field' shortcode due to insufficient input sanitization and output escaping. 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, 5.7, update to a version that addresses the insufficient input sanitization and output escaping issue in the 'field' shortcode to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the 'field' shortcode for users with Contributor-level access and above until a patch is available.
