Which packages are affected by GHSA-247v-7cw6-q57v?

GHSA-247v-7cw6-q57v affects the following packages: devcode-it/openstamanager (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-247v-7cw6-q57v?

No patched version of devcode-it/openstamanager has shipped for GHSA-247v-7cw6-q57v yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

How do I detect GHSA-247v-7cw6-q57v in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for devcode-it/openstamanager. 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.

How do I mitigate GHSA-247v-7cw6-q57v if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-247v-7cw6-q57v?

O3 pinpoints whether GHSA-247v-7cw6-q57v is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-247v-7cw6-q57v actively exploited in the wild?

No public exploit code has been indexed for GHSA-247v-7cw6-q57v yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-247v-7cw6-q57v?

GHSA-247v-7cw6-q57v has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 41th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-247v-7cw6-q57v?

GHSA-247v-7cw6-q57v is classified as Missing Authentication (CWE-306). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-247v-7cw6-q57v published, and has it been updated?

GHSA-247v-7cw6-q57v was published on March 3, 2026 and was last updated on March 4, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Summary

A privilege escalation and authentication bypass vulnerability in OpenSTAManager allows any attacker to arbitrarily change a user's group (idgruppo) by directly calling modules/utenti/actions.php. This can promote an existing account (e.g. agent) into the Amministratori group as well as demote any user including existing administrators.

Details

modules/utenti/actions.php is reachable directly via http://<IP>:8080/modules/utenti/actions.php and processes privileged information without requiring any authentication or authorization checks on fields like idgruppo. As a result, an attacker can submit a crafted POST request that updates the targets record and assigns it to the administrator group.

The file explicitly sets:

$skip_permissions = true;
include_once __DIR__.'/../../core.php';

core.php then invokes:

Permissions::skip();

Thus, disabling any authentication and permission enforcement. As a result, this file processes operations based on the op parameter in the POST request, not only update_user. Sensitive fields like idgruppo and others can be updated without verifying anything.

PoC

A target username exists, such as "agent" with an ID of 4. No authentication or cookies are required. Send the following POST request via Burp Suite or similar: <img width="1094" height="255" alt="image" src="https://github.com/user-attachments/assets/2e8cb148-1b5d-4e5c-9c73-05ed75d64188" /> The target's group is updated in the database. Verify the changes in the database before and after the POST request: <img width="1053" height="430" alt="image" src="https://github.com/user-attachments/assets/49f63ca0-8a04-4dd1-b27c-69699d2ce26f" /> Changes also visible in the administrator panel, they have been moved from the Agenti group to Amministratori.

Impact

An unauthenticated attacker can assign administrator privileges to existing users, modify group memberships, enable/disable accounts and other operations that are exposed in the file. This can lead to a full compromise of the application.
