Description
The Gutentor – Gutenberg Blocks – Page Builder for Gutenberg Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.5.5 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.
