Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-287.

Summary

An Improper Authentication vulnerability in the /api/Cdn/GetFile endpoint of linqi allows unauthenticated, remote attackers to bypass file access controls. The ValidateAnonFileAccess function incorrectly grants access if an 'AnonFile' query parameter containing exactly 256 characters is provided. While this flaw allows bypassing the intended authorization check, the actual security impact is negligible; the exposed resources are strictly limited to minified JavaScript and CSS files that contain no sensitive data and are already publicly accessible via a standard CDN.
