GHSA-247v-7cw6-q57v — devcode-it/openstamanager
CRITICALGHSA-247v-7cw6-q57v is a critical-severity (CVSS 9.8) Missing Authentication vulnerability in devcode-it/openstamanager. No vendor fix is recorded yet; mitigation options are listed below.
OpenSTAManager affected by unauthenticated privilege escalation via modules/utenti/actions.php
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

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.
How urgent is this, really
GHSA-247v-7cw6-q57v plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,333 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for devcode-it/openstamanager, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
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.
Mitigate without a patch
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-247v-7cw6-q57v can be triaged on real exposure rather than presence alone.
Tailored to GHSA-247v-7cw6-q57v. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
