Bludit CMS 3.22.0 及之前版本存在一个授权绕过漏洞，允许具有“作者”（Author）角色的已认证用户通过向未受保护的 AJAX 端点提供任意的 UUID 参数，枚举并删除属于其他用户（包括管理员）所拥有页面的媒体文件。攻击者可以通过 content-get-list 端点获取所有用户的页面 UUID，然后向 bl-kernel/ajax/ 下的 list-images 和 delete-image 端点提交构造的 POST 请求，从而访问并销毁其自有页面之外的媒体文件，从而绕过 IMAGE_REST

Vulnerability Title
Bludit CMS 3.22.0 Authorization Bypass via list-images/delete-image AJAX Endpoints
Source: CVE Program / CVE List V5
Vulnerability Description
Bludit CMS through 3.22.0 contains an authorization bypass vulnerability that allows authenticated users with the Author role to enumerate and delete media files belonging to pages owned by other users, including administrators, by supplying arbitrary uuid parameters to unprotected AJAX endpoints. Attackers can retrieve page UUIDs for all users via the content-get-list endpoint and then submit crafted POST requests to the list-images and delete-image endpoints in bl-kernel/ajax/ to access and destroy media files outside their own pages, bypassing the IMAGE_RESTRICT isolation control.
