Post and Page Builder by BoldGrid – Visual Drag and Drop Editor < 1.26.5 - Authenticated (Contributer+) Stored Cross-Site Scripting

Description

The Post and Page Builder by BoldGrid – Visual Drag and Drop Editor plguin for WordPress is vulnerable to Stored Cross-Site Scripting via an unknown parameter in versions up to, and including, 1.26.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
