Description

The Add Custom Body Class plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'add_custom_body_class' value in versions up to, and including, 1.4.1 due to insufficient input sanitization and output escaping. This makes it possible for 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.

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

  • anilankola Add Custom Body Class — Up to and including 1.4.1
  • anilankola add_custom_body_class — Up to and including 1.4.1
