CVE-2026-3669 Overview
A security vulnerability has been detected in Freedom Factory dGEN1 up to version 20260221. This impacts the function AlarmService of the component com.dgen.alarm. Such manipulation leads to improper authorization (CWE-266: Incorrect Privilege Assignment). The attack needs to be performed locally. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Critical Impact
Local attackers with low privileges can exploit improper authorization in the AlarmService component to gain unauthorized access or escalate privileges on affected dGEN1 devices.
Affected Products
- Freedom Factory dGEN1 up to version 20260221
- com.dgen.alarm component (AlarmService function)

Technical Details for CVE-2026-3669
Vulnerability Analysis
This vulnerability represents an Improper Authorization flaw (CWE-266: Incorrect Privilege Assignment) in the Freedom Factory dGEN1 device. The vulnerable component is located in the com.dgen.alarm package, specifically within the AlarmService function. Due to incorrect privilege assignment, an attacker with local access and low-level privileges can manipulate the service to perform actions beyond their authorized scope.
The vulnerability requires local access to exploit, meaning an attacker must have some form of access to the target system. Once access is obtained, the improper authorization controls allow the attacker to compromise confidentiality, integrity, and availability of the affected system to a limited extent.
Root Cause
The root cause of this vulnerability lies in incorrect privilege assignment within the AlarmService function of the com.dgen.alarm component. The service fails to properly validate and enforce authorization controls, allowing users with insufficient privileges to access or manipulate functionality that should be restricted.
Attack Vector
The attack vector for CVE-2026-3669 is local, requiring the attacker to have existing access to the target dGEN1 device. The exploitation requires low privileges and no user interaction to execute.
The vulnerability mechanism involves improper authorization checks in the AlarmService component. When the service processes requests, it fails to properly verify whether the requesting user has sufficient privileges, allowing unauthorized operations. Technical details and proof-of-concept code have been publicly disclosed via GitHub Gist. Additional technical information is available through the VulDB CTI Advisory.
Detection Methods for CVE-2026-3669
Indicators of Compromise
- Unusual activity or unauthorized access attempts targeting the com.dgen.alarm component
- Unexpected privilege escalation events on dGEN1 devices
- Anomalous behavior or modifications to AlarmService functionality
- Log entries showing unauthorized service calls to AlarmService
Detection Strategies
- Monitor system logs for unauthorized access attempts to the AlarmService function
- Implement access control monitoring to detect privilege abuse patterns
- Deploy endpoint detection rules that flag unexpected interactions with com.dgen.alarm
- Review user activity logs for anomalous local access patterns on dGEN1 devices
Monitoring Recommendations
- Enable verbose logging for the com.dgen.alarm component to capture detailed service interactions
- Implement real-time alerting for any unauthorized privilege escalation attempts
- Regularly audit access permissions on dGEN1 devices
- Deploy SentinelOne agents to provide behavioral analysis and threat detection for affected devices
How to Mitigate CVE-2026-3669
Immediate Actions Required
- Restrict local access to dGEN1 devices to only authorized personnel
- Implement additional access controls to limit interaction with the AlarmService component
- Monitor affected devices for signs of exploitation
- Review and audit user privileges on dGEN1 systems
- Consider network segmentation to limit exposure of vulnerable devices
Patch Information
No official patch is currently available from Freedom Factory. The vendor was contacted early about this disclosure but did not respond in any way. Organizations should monitor vendor communications for future security updates and apply patches immediately when available.
For additional technical details, refer to:
Workarounds
- Implement strict access controls to limit local access to dGEN1 devices
- Use additional authorization mechanisms or wrapper services around the AlarmService component
- Deploy application-level firewalls or access control lists to restrict service interactions
- Consider isolating affected dGEN1 devices on a separate network segment until a patch is available
# Example access restriction configuration
# Limit local access to authorized users only
chmod 750 /path/to/dgen1/alarm/service
chown root:authorized_group /path/to/dgen1/alarm/service
