On KEV
Description
Snipe-IT is an IT asset/license management system. Prior to 8.6.2, default.blade.php renders header_color and related branding color settings inside a CSS style block with HTML escaping that is insufficient for the CSS context, allowing a superadmin to inject arbitrary CSS that affects authenticated users on subsequent page loads when Content Security Policy is disabled. This issue is fixed in version 8.6.2.
