Published May 5, 2026 · Updated May 6, 2026 · Assigned by Wordfence

Description

The Gutenverse – Ultimate WordPress FSE Blocks Addons & Ecosystem plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'separatorIconSVG' parameter in versions up to, and including, 3.5.3 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.
