MineAdmin Vulnerable to Path Traversal via Unsanitized identifier in Plugin Install/Uninstall

CVE-2026-55224GHSA-59xm-4m8c-g3xj

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (mineadmin/mineadmin 3.2.0-alpha.2), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Path Traversal via Unsanitized Identifier in Plugin Install/Uninstall Summary The app-store plugin service concatenates unsanitized user-supplied identifier values directly into file system paths. An attacker can use path traversal sequences (e.g., ../) to read, install, or uninstall plugins from arbitrary directories, and potentially execute arbitrary composer commands. Vulnerable Code File: plugin/mine-admin/app-store/src/Service/Service.php File: plugin/mine-admin/app-store/src/Controller/IndexController.php (lines 25-26) Proof of Concept Impact - Path traversal enables reading directory existence outside the plugin directory - Plugin::install() with a traversed identifier may run composer commands on arbitrary directories - Combined with GM-4340 (missing PermissionMiddleware), any authenticated user can exploit this - Could lead to arbitrary code execution depending on Plugin::install() implementation Remediation Validate and sanitize the identifier parameter to reject path…

# Patch Next advisory brief: CVE-2026-55224

Advisory: MineAdmin Vulnerable to Path Traversal via Unsanitized identifier in Plugin Install/Uninstall
IDs: CVE-2026-55224, GHSA-59xm-4m8c-g3xj
Record: https://patchnext.com/advisories/cve-2026-55224 (revision 3, source checked 26 Oct 2026, 14:50 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: mineadmin/mineadmin 3.2.0-alpha.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist mineadmin/mineadmin: affected < 3.2.0-alpha.2; fixed in 3.2.0-alpha.2

## Suggested inspection (read-only)
- Packagist mineadmin/mineadmin: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on mineadmin/mineadmin.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-59xm-4m8c-g3xj (OSV record GHSA-59xm-4m8c-g3xj lists affected ranges: Packagist mineadmin/mineadmin >=0 <3.2.0-alpha.2 (fixed))
- Verified: https://github.com/advisories/GHSA-59xm-4m8c-g3xj (GitHub-reviewed advisory GHSA-59xm-4m8c-g3xj lists affected ranges: Packagist mineadmin/mineadmin >=0 <3.2.0-alpha.2)
