## Technical details

The Cozy Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the 'icon.view' block attribute within the Advanced Categories component. An authenticated attacker with contributor-level permissions or higher can inject arbitrary web scripts into a page's block attributes. Because the plugin fails to properly neutralize this input before rendering it on the front end, the script executes in the context of any user's session who views the compromised page. This vulnerability is present in all versions up to and including 2.2.11.
