Description

The Cozy Blocks – Website Builder for WordPress Block Editor | Gutenberg Blocks, Patterns & Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'content (block attribute icon.view / icon.layout / icon.gap)' parameter in all versions up to, and including, 2.2.27 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. Although wp_kses_post is applied on save, it does not neutralize a quote-only attribute-breakout payload containing no '<' character, leaving the block comment and its decoded JSON attributes intact and exploitable at render time.
