Description

The Page Builder: KingComposer plugin for WordPress is vulnerable to authorization bypass in versions up to, and including, 2.9.3. This is due to a security nonce being leaked in the '/wp-admin/index.php' page. This makes it possible for authenticated attackers to change arbitrary WordPress options, delete arbitrary files/folders, and inject arbitrary content.

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

  • kingthemes Page Builder: KingComposer – Free Drag and Drop page builder by King-Theme — Up to and including 2.9.3
  • king-theme page_builder_kingcomposer — Up to and including 2.9.3
