CVE-2026-3675 Overview
A vulnerability has been identified in Freedom Factory dGEN1 up to version 20260221. This security flaw affects the FakeAppReceiver function within the org.ethosmobile.ethoslauncher component, leading to improper authorization. The vulnerability is classified as CWE-266 (Incorrect Privilege Assignment), which occurs when a product incorrectly assigns privileges to a particular actor, creating an unintended sphere of control.
Critical Impact
Local attackers with low privileges can exploit this improper authorization vulnerability to gain unauthorized access to functionality or data within the dGEN1 device, potentially compromising data confidentiality, integrity, and availability.
Affected Products
- Freedom Factory dGEN1 up to version 20260221
- org.ethosmobile.ethoslauncher component
- FakeAppReceiver function

Technical Details for CVE-2026-3675
Vulnerability Analysis
This vulnerability stems from improper authorization controls within the Freedom Factory dGEN1 mobile device. The affected FakeAppReceiver component in org.ethosmobile.ethoslauncher fails to properly validate the privileges of actors attempting to access protected functionality. This represents a classic case of CWE-266 (Incorrect Privilege Assignment), where the application grants privileges beyond what should be permitted based on the actor's actual authorization level.
The exploit has been publicly disclosed and proof-of-concept code is available, increasing the risk of exploitation in the wild. Notably, the vendor was contacted about this disclosure but did not respond, leaving users without official guidance or patches.
Root Cause
The root cause of CVE-2026-3675 lies in the FakeAppReceiver function's failure to properly enforce authorization checks. The component appears to accept and process requests without adequately verifying that the requesting entity has the appropriate privileges to perform the requested action. This incorrect privilege assignment allows lower-privileged local users to execute operations that should be restricted to higher-privilege contexts.
Attack Vector
This vulnerability requires local access to exploit. An attacker with low-privilege access to the dGEN1 device can manipulate the FakeAppReceiver component to bypass authorization controls. The attack does not require user interaction, making it easier to exploit once local access is obtained.
The vulnerability affects confidentiality, integrity, and availability of the local system, though no impact to downstream systems has been identified. Technical details and proof-of-concept code are available through the GitHub Gist PoC published by the security researcher.
Detection Methods for CVE-2026-3675
Indicators of Compromise
- Unusual activity or unexpected behavior from the org.ethosmobile.ethoslauncher application
- Unauthorized access attempts to FakeAppReceiver component from low-privilege processes
- Suspicious privilege escalation events on dGEN1 devices
- Unexpected modifications to launcher settings or configurations
Detection Strategies
- Monitor Android system logs for anomalous Intent broadcasts targeting FakeAppReceiver
- Implement application-level logging to track authorization decisions within the ethoslauncher component
- Deploy endpoint detection solutions capable of identifying privilege escalation attempts on Android devices
- Review device access logs for patterns consistent with local exploitation attempts
Monitoring Recommendations
- Enable verbose logging for the org.ethosmobile.ethoslauncher application to capture authorization events
- Monitor for unexpected inter-process communication involving the affected component
- Establish baseline behavior for dGEN1 devices to identify deviations that may indicate exploitation
How to Mitigate CVE-2026-3675
Immediate Actions Required
- Limit physical and local access to dGEN1 devices to trusted personnel only
- Review and restrict user privileges on affected devices to minimize attack surface
- Consider disabling or restricting the org.ethosmobile.ethoslauncher application if not critical for operations
- Monitor devices for signs of exploitation using the detection strategies outlined above
Patch Information
As of the last update on 2026-03-09, no official patch has been released by Freedom Factory. The vendor was contacted regarding this vulnerability disclosure but did not respond. Users should monitor VulDB entry #349571 for updates on vendor response and potential patches.
Workarounds
- Implement strict access controls to limit which users can interact with the dGEN1 device locally
- Consider network segmentation to isolate dGEN1 devices from untrusted systems
- Deploy mobile device management (MDM) solutions to enforce security policies and monitor device behavior
- If possible, disable or remove the org.ethosmobile.ethoslauncher application until a patch is available
# Example: Restrict app permissions via ADB (requires root/developer access)
# Disable the vulnerable component if not required
adb shell pm disable org.ethosmobile.ethoslauncher/.FakeAppReceiver
# List current permissions for the application
adb shell dumpsys package org.ethosmobile.ethoslauncher | grep permission
