CVE-2026-11345 linqi GmbH CVE debrief

CVE-2026-11345 is an Improper Authentication vulnerability in the /api/Cdn/GetFile endpoint of linqi. This flaw allows unauthenticated, remote attackers to bypass file access controls by providing an 'AnonFile' query parameter containing exactly 256 characters. However, the actual security impact is negligible as the exposed resources are limited to minified JavaScript and CSS files that contain no sensitive data and are already publicly accessible via a standard CDN.
