MEDIUM

Bold Page Builder <= 5.3.6 - Authenticated Stored Cross-Site Scripting via Additional Settings Parameter

Title source: llm

Description

The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘additional_settings’ parameter in all versions up to, and including, 5.3.6 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.
