CVE-2026-92570 Overview
CVE-2026-92570 is an authorization bypass vulnerability in reNgine through version 2.2.0, an open-source automated reconnaissance framework. The flaw resides in the GetFileContents API endpoint, which fails to enforce role-based access control before returning bundled configuration files. Any authenticated user, including low-privilege Auditor accounts, can query the endpoint to read configuration files containing third-party API keys. Exposed credentials include integrations for SecurityTrails, Shodan, Censys, VirusTotal, BinaryEdge, and Hunter. The issue is tracked as CWE-862: Missing Authorization.
Critical Impact
Authenticated low-privilege users can exfiltrate third-party API keys for reconnaissance services, enabling secondary abuse of those accounts and quota theft.
Affected Products
- reNgine versions up to and including 2.2.0
- Deployments exposing the GetFileContents API endpoint
- Instances using bundled integrations for SecurityTrails, Shodan, Censys, VirusTotal, BinaryEdge, and Hunter

Technical Details for CVE-2026-92570
Vulnerability Analysis
reNgine exposes a GetFileContents API view designed to return the contents of specific tool configuration files used during recon workflows. The view accepts an authenticated request and returns configuration data without validating whether the requesting user has an administrative role. As a result, any account within the application, including the Auditor role intended for read-only oversight, can request the endpoint and receive sensitive files.
The returned files include third-party API keys stored server-side to authenticate outbound requests to reconnaissance services. An attacker in possession of these keys can pivot to the external SaaS accounts, consume paid API quota, retrieve historical reconnaissance data, and correlate the victim organization's scanning activity. See the VulnCheck advisory for full context.
Root Cause
The root cause is a missing authorization check in the API view defined in web/api/views.py. The handler relies only on authentication and does not evaluate the user's role before reading and returning file contents referenced by keys defined in web/reNgine/settings.py.
Attack Vector
Exploitation requires network access to the reNgine web interface and a valid session for any application role. The attacker issues an authenticated request to the GetFileContents endpoint specifying an allowed configuration file identifier. The server returns the raw contents, exposing embedded API keys that the attacker extracts and reuses against upstream reconnaissance services. Further discussion is available in reNgine issue #1554.
No verified proof-of-concept code is published in the referenced advisories. Refer to the linked source snippets in the reNgine repository for exact request handling behavior.

Stop Identity AttacksDetection Methods for CVE-2026-92570
Indicators of Compromise
- Authenticated HTTP requests to the GetFileContents API endpoint originating from non-administrator accounts
- Unexpected outbound API calls to SecurityTrails, Shodan, Censys, VirusTotal, BinaryEdge, or Hunter from IP addresses outside the reNgine host
- Anomalous quota consumption or billing alerts from integrated third-party reconnaissance services
Detection Strategies
- Review reNgine application and web server access logs for calls to the GetFileContents endpoint and correlate the requesting user against role assignments
- Alert on any access to this endpoint from users not holding administrative privileges
- Cross-reference reNgine API access with the API key usage dashboards provided by each integrated third-party service
Monitoring Recommendations
- Enable verbose audit logging in reNgine and forward logs to a centralized SIEM for retention and correlation
- Monitor for use of exfiltrated API keys from source addresses that do not match the sanctioned reNgine deployment
- Track authentication events and privilege changes for Auditor and other low-privilege accounts that could be leveraged for exploitation
How to Mitigate CVE-2026-92570
Immediate Actions Required
- Restrict network access to the reNgine web interface to trusted administrators until a patched release is deployed
- Rotate all third-party API keys referenced in reNgine configuration files, including SecurityTrails, Shodan, Censys, VirusTotal, BinaryEdge, and Hunter
- Audit reNgine user accounts and remove unused or unnecessary Auditor and low-privilege accounts
- Review third-party service usage logs for signs of key abuse and revoke any keys with anomalous activity
Patch Information
At the time of publication, no fixed release is identified in the referenced advisories. Monitor the reNgine GitHub repository and issue #1554 for a patched version and apply it as soon as it is available.
Workarounds
- Place reNgine behind a reverse proxy or VPN that limits access to trusted administrator IP ranges
- Remove or invalidate API keys from the bundled configuration files if the corresponding integrations are not required
- Apply a local patch that adds a role-based permission check to the GetFileContents view, rejecting requests from non-administrator users
# Example network restriction using host firewall (adapt to your environment)
sudo ufw default deny incoming
sudo ufw allow from 10.0.0.0/24 to any port 443 proto tcp
sudo ufw enable
