Description

The Colibri Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the colibri_blog_posts shortcode in all versions up to, and including, 1.0.345 due to insufficient input sanitization and output escaping on user supplied attributes. 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

  • extendthemes Colibri Page Builder — Up to and including 1.0.345
