Description

The TinyMCE Custom Styles WordPress plugin before 1.1.4 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • Unknown TinyMCE Custom Styles — Before 1.1.4
  • tinymce_custom_styles_project tinymce_custom_styles — Before 1.1.4
