CVE-2021-24826 Information

Description

The Custom Content Shortcode WordPress plugin before 4.0.2 does not escape custom fields before outputting them which could allow Contributor+ (v < 4.0.1) or Admin+ (v < 4.0.2) users to perform Cross-Site Scripting attacks even when the unfiltered_html is disallowed. Please note that such attack is still possible by admin+ in single site blogs by default (but won’t be when the unfiltered_html is disallowed)
