CRITICALGin-vue-admin subject to Remote Code Execution via file upload vulnerability
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
Impact
Gin-vue-admin < 2.5.4 has File upload vulnerabilities。 File upload vulnerabilities are when a web server allows users to upload files to its filesystem without sufficiently validating things like their name, type, contents, or size. Failing to properly enforce restrictions on these could mean that even a basic image upload function can be used to upload arbitrary and potentially dangerous files instead. This could even include server-side script files that enable remote code execution.

For more information
The plugin installation function of Gin-Vue-Admin allows users to download zip packages from the plugin market and upload them for installation. This function has an arbitrary file upload vulnerability. A malicious attacker can upload a constructed zip package to traverse the directory and upload or overwrite arbitrary files on the server side.
The affected code https://github.com/flipped-aurora/gin-vue-admin/blob/main/server/service/system/sys_auto_code.go line 880 called the utils.Unzip method
paths, err := utils.Unzip(GVAPLUGPINATH+file.Filename, GVAPLUGPINATH)
paths = filterFile(paths)
var webIndex = -1
var serverIndex = -1
for i := range paths {
paths[i] = filepath.ToSlash(paths[i])
pathArr := strings.Split(paths[i], "/")
ln := len(pathArr)
if ln < 2 {
continue
}
if pathArr[ln-2] == "server" && pathArr[ln-1] == "plugin" {
serverIndex = i
}
if pathArr[ln-2] == "web" && pathArr[ln-1] == "plugin" {
webIndex = i
}
}
if webIndex == -1 && serverIndex == -1 {
zap.L().Error("非标准插件，请按照文档自动迁移使用")
return webIndex, serverIndex, errors.New("非标准插件，请按照文档自动迁移使用")
}
...
The https://github.com/flipped-aurora/gin-vue-admin/blob/main/server/utils/zip.go code defines the utils.Unzip method
//解压
func Unzip(zipFile string, destDir string) ([]string, error) {
zipReader, err := zip.OpenReader(zipFile)
var paths []string
if err != nil {
return []string{}, err
}
defer zipReader.Close()
for _, f := range zipReader.File {
fpath := filepath.Join(destDir, f.Name)
paths = append(paths, fpath)
if f.FileInfo().IsDir() {
os.MkdirAll(fpath, os.ModePerm)
...
It can be analyzed that after uploading a zip compressed file, the Unzip method will be called to decompress the compressed file, and then judge whether the compressed file contains the fixed directory structure of server, web, and plugin.
Whether the zip file is correct or not, it will be decompressed first. If the directory does not exist, it will be created automatically. Therefore, malicious zip packages can be constructed, and directory traversal can be performed during automatic decompression to upload or overwrite any file.
Use the Zip Slip vulnerability to construct a malicious zip package with ../../../../ filenames, and upload the malicious zip package to trigger the 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/server. 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.
Fix
Update github.com/flipped-aurora/gin-vue-admin/server to 2.5.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7gc4-r5jr-9hxv is resolved across your whole dependency graph.
Workarounds
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 GHSA-7gc4-r5jr-9hxv 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 GHSA-7gc4-r5jr-9hxv. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-7gc4-r5jr-9hxv in your dependencies?
O3 detects GHSA-7gc4-r5jr-9hxv across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
