Gin-vue-admin has arbitrary file upload vulnerability caused by path traversal
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/flipped-aurora/gin-vue-admin. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of github.com/flipped-aurora/gin-vue-admin has shipped for CVE-2026-22786 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-22786 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-22786. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
