Summary

Cozy Blocks <= 2.2.11 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'postMeta.font.size' Block Attribute

Details

The Cozy Blocks – Page Builder for Gutenberg Editor & FSE with 600+ Patterns, 58 Blocks & Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'postMeta.font.size' Block Attribute in all versions up to, and including, 2.2.11 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.
