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)

Affected products and versions

  • Unknown Custom Content Shortcode — From 4.0.2 (including) to 4.0.2 (excluding)
  • custom_content_shortcode_project custom_content_shortcode — Before 4.0.2
