Description

The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin 'bt_bb_tabs' shortcode in all versions up to, and including, 5.5.1 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.
