MITRE ATT&CK
2 techniques across 2 tactics: Discovery, Collection The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Requires an authenticated request bearing a valid JWT to the MineAdmin admin API (the /admin/plugin/store/install, /uninstall, and /download endpoints are guarded by AccessTokenMiddleware). The critical enabling condition is the absence of PermissionMiddleware on these routes (GM-4340), so ANY authenticated user regardless of role - not only administrators - can reach the vulnerable code. Affected deployments are MineAdmin (composer package mineadmin/mineadmin) at versions < 3.2.0-alpha.2. Exploitation is limited by needing valid credentials/token; it is not anonymously reachable despite the vendor's PR:N rating. The most severe (code-execution) outcome further depends on the behavior of Plugin::install()/composer on the traversed path. |
| Impact | This is a moderately high-priority issue that warrants prompt patching but is not an internet-wide emergency. The vendor CVSS 4.0 vector (8.7, AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H) implies unauthenticated network exploitation, but this CONFLICTS with the source evidence: the vulnerable IndexController is protected by AccessTokenMiddleware, and the advisory/patch explicitly state the flaw is reachable because PermissionMiddleware was missing (GM-4340), meaning ANY authenticated user - not an anonymous one - can exploit it. A valid JWT bearer token is required, so PR:N overstates exposure; PR:L is more accurate. Positive signals: a public PoC exists (curl commands in the advisory), a vendor patch is available (v3.2.0-alpha.2, commit ca41902), and the finding is confirmed reproduced in Docker. There is no CISA KEV listing and no EPSS score provided, so there is no evidence of active or automated exploitation - this reads as a real, confirmed, exploitable bug rather than a mass-exploited one. The 'RCE' tag and 'arbitrary code execution' claim are conditional ('depending on Plugin::install() implementation' / composer command execution), so the highest impact is plausible but not fully proven from the provided data. |
| Exploit ScenarioDerived | An attacker who holds any valid session token for a MineAdmin instance (e.g., a low-privileged back-office user, or an attacker who has phished/obtained one JWT) sends a POST to /admin/plugin/store/install with an identifier of '../app'. Because the identifier is concatenated into a filesystem path without sanitization and no permission check gates the endpoint, the request resolves outside the plugin directory and invokes Plugin::install() on an arbitrary path, potentially running composer commands. A public proof-of-concept (curl requests) is included in the GitHub advisory. |

Alert meAnalysisAIv2 – Sep 30, 2026
Path traversal in the MineAdmin app-store plugin service lets any authenticated API user read, install, or uninstall plugins from directories outside the intended plugin folder by supplying traversal sequences (e.g., ../) in the identifier parameter of the /admin/plugin/store/download, /install, and /uninstall endpoints. The enabling condition is the absence of PermissionMiddleware on those routes (GM-4340), so exploitation requires only a valid JWT, not administrator privileges - the vendor's CVSS 4.0 vector scores PR:N, but this assessment treats the issue as authenticated (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:H) because AccessTokenMiddleware still guards the endpoints. Publicly available exploit code exists and the finding was reproduced and validated in a Docker environment; the most severe outcome (code execution) additionally depends on how Plugin::install() invokes composer on the traversed path.
Earlier versions of this analysis (1)
Path traversal via unsanitized plugin identifier in MineAdmin's app-store service enables any authenticated user to read directory existence outside the plugin root, trigger Plugin::install() and Plugin::uninstall() on arbitrary filesystem paths, and potentially execute arbitrary Composer commands. Affected versions are all releases of composer/mineadmin/mineadmin prior to v3.2.0-alpha.2. Compounded by a missing PermissionMiddleware on the plugin store controller (GM-4340), any bearer-token holder - not just administrators - can reach the vulnerable endpoints. A proof-of-concept is publicly available and the vulnerability has been reproduced in a Docker environment.
RemediationAI
Upgrade MineAdmin to 3.2.0-alpha.2 or later, which is the vendor-released patched version (fix commit ca41902a2a5422676227e5088f4cc1dec06044f1, PR #728); the patch adds a normalizeIdentifier() allowlist using the regex /\A[A-Za-z0-9_-]+\/[A-Za-z0-9_-]+\z/ before any path concatenation, replaces ad-hoc BASE_PATH . '/plugin/' paths with Plugin::PLUGIN_PATH, and adds assertSafeZipEntries()/isUnsafeZipEntryName()/isZipEntrySymlink() checks that reject '..', absolute paths, drive letters, null bytes, and Unix symlink entries during zip extraction. Note that 3.2.0-alpha.2 is a pre-release build, so test the upgrade in staging before production rollout if your policy restricts alpha versions. Because the patch also introduces PermissionMiddleware and a #[Permission(code: 'plugin:store')] attribute on the controller, backporting only the identifier validation and zip checks is possible, but the permission guard should be applied as well to close GM-4340. As a compensating control when an immediate upgrade is not possible: register PermissionMiddleware on the admin/plugin/store route prefix manually (or block that prefix at the reverse proxy/ingress), which stops non-privileged authenticated users from reaching the vulnerable methods but does not stop a compromised administrator account; and temporarily disable the app-store plugin entirely, which removes the attack surface at the cost of plugin management functionality. Additional hardening with a trade-off of administrative overhead: restrict the admin API to trusted network ranges, rotate and shorten JWT lifetimes/audience, and audit logs for identifiers containing '../', '/', or backslash sequences against /admin/plugin/store/install, /uninstall, and /download. Do not rely on generic input filtering at a WAF as a primary fix, since the traversal is simple and easily obfuscated. Given a publicly available exploit and validated Docker reproduction, patch or apply the permission-group and route-blocking workarounds promptly; per this assessment this is a moderately high-priority issue warranting prompt patching rather than an internet-wide emergency.

Technical ContextAI · show details
The root cause is CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), introduced in the PHP plugin/mine-admin/app-store/src/Service/Service.php class, which concatenates the user-supplied identifier parameter directly into filesystem paths such as BASE_PATH . '/plugin/' . $params['identifier'] and then passes the same unvalidated string to Plugin::install() / Plugin::uninstall(). Because '../' sequences are not stripped, an identifier like '../app' resolves to BASE_PATH/app, and '../../etc' escapes the application root entirely, allowing directory-existence probing, arbitrary plugin install/uninstall, and - through Plugin::install()'s composer workflow - the potential for arbitrary code execution on the target host. A second, related attack surface exists in uploadLocalApp(), where a zip archive is extracted into Plugin::PLUGIN_PATH without validating entry names or symlink attributes, permitting zip-slip and symlink-based writes. The control-plane weakness is architectural: the IndexController declares only AccessTokenMiddleware on the 'admin/plugin/store' route prefix, omitting PermissionMiddleware (tracked separately as GM-4340), so any principal holding a valid JWT - regardless of role - reaches the vulnerable code. Deployment is via Composer (CPE pkg:composer/mineadmin_mineadmin), and the stack is PHP (Hyperf/Swoole-style runtime, as suggested by the 9501 listener and attribute-based middleware).

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
// Line 32 - download(): path traversal via identifier
public function download(array $params): bool
{
if (empty($params['identifier']) || empty($params['version'])) {
$this->throwParamsFail();
}
$service = make(AppStoreServiceImpl::class);
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')) {
$this->throwAppInstalled();
}
Plugin::install($params['identifier']); // May run composer commands with traversal path
return true;
}
// 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;
}File: plugin/mine-admin/app-store/src/Controller/IndexController.php (lines 25-26)
#[Controller(prefix: 'admin/plugin/store')]
#[Middleware(middleware: AccessTokenMiddleware::class, priority: 100)]

-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

- 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 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.

Executive ViewAI
The MineAdmin app-store plugin service contains a path traversal vulnerability (CVE-2026-55224) that allows any authenticated API user to read, install, or uninstall plugins outside the intended directory, potentially leading to code execution. Because exploitation requires only a valid JWT and publicly available exploit code exists, internal users without administrative privileges can compromise the platform's integrity and availability. Leadership should prioritize immediate remediation, as affected systems may suffer unauthorized plugin manipulation and data exposure.
