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

- Also known as: GO-2026-4313, GHSA-3558-J79F-VVM6
- Severity: CVSS 7.3 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2026-01-12 · Updated: 2026-01-13

## Affected

- flipped-aurora gin-vue-admin: through 2.8.7
- github.com/flipped-aurora/gin-vue-admin (Go): all versions
- github.com/flipped-aurora/gin-vue-admin (Go): through 2.8.7

## Description

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.
