Gutenverse – Ultimate WordPress FSE Blocks Addons & Ecosystem <= 3.4.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'imageLoad'

The Gutenverse – Ultimate WordPress FSE Blocks Addons & Ecosystem plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'imageLoad' parameter in versions up to, and including, 3.4.6 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.
