Post and Page Builder by BoldGrid – Visual Drag and Drop Editor Plugin < 1.26.3 - Authenticated (Contributor+) Stored Cross-Site Scripting

Description

The Post and Page Builder by BoldGrid – Visual Drag and Drop Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Block HTML in all versions up to, and including, 1.26.2 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.
