CVE-2024-33863Network attack vector

Unauthenticated file disclosure via unchecked file paths

Published May 14, 2024 · Updated Feb 13, 2025

Local file inclusion in linqi for Windows before 1.4.0.1 allows remote attackers to read arbitrary server files through /api/Cdn/GetFile. The endpoint accepts attacker-controlled file paths without sufficient validation before retrieving files from the server file system. No authentication or user interaction is required, and the demonstrated consequence is disclosure of local file contents.
