CVE-2026-22786

CVE-2026-22786: Gin-vue-admin has arbitrary file upload vulnerability caused by path traversal

Gin-vue-admin is a backstage management system based on vue and gin. Gin-vue-admin <= v2.8.7 has a path traversal vulnerability in the breakpoint resume upload functionality. Attacker can upload any files on any directory. In the breakpoint_continue.go file, the MakeFile function accepts a fileName parameter through the /fileUploadAndDownload/breakpointContinueFinish API endpoint and directly concatenates it with the base directory path (./fileDir/) using os.OpenFile() without any validation for directory traversal sequences (e.g., ../). An attacker with file upload privileges could exploit this vulnerability.

Root Cause Analysis

The vulnerability analysis identified a path traversal weakness in the file upload functionality of Gin-vue-admin. The root cause was insufficient input validation on parameters used to construct file and directory paths. Specifically, the MakeFile, BreakPointContinue, and RemoveChunk functions in server/utils/breakpoint_continue.go accepted fileName and FileMd5 parameters from the user without sanitizing them for directory traversal sequences like ../. This allowed an authenticated attacker with file upload privileges to write, create, or delete files and directories in arbitrary locations on the server, potentially leading to remote code execution. The patch addresses this by adding explicit checks in all three functions to reject any input containing ...
