Authenticated file disclosure via unchecked fileName traversal
Published Aug 25, 2025 · Updated Aug 25, 2025
Path traversal in lostvip-com ruoyi-go 2.0 and 2.1 allows remote authenticated users to read arbitrary server files. DownloadTmp and DownloadUpload use the request's fileName value to select a filesystem path without confining the resolved path to the intended directory. A low-privileged authenticated session is required, and exploitation exposes file contents without modifying them or interrupting service.
