CVE-2026-21014: Samsung Camera Auth Bypass Vulnerability

CVE-2026-21014 Overview

CVE-2026-21014 is an improper access control vulnerability in Samsung Camera that allows a local attacker to access location data without proper authorization. This vulnerability exists in Samsung Camera versions prior to 16.5.00.28 and requires user interaction to trigger the exploit.

Critical Impact

Local attackers can gain unauthorized access to sensitive location data stored or processed by the Samsung Camera application, potentially exposing user privacy and enabling tracking or surveillance activities.

Affected Products

• Samsung Camera versions prior to 16.5.00.28

Technical Details for CVE-2026-21014

Vulnerability Analysis

This vulnerability stems from improper access control mechanisms within the Samsung Camera application. The application fails to properly validate or restrict access to location data, allowing unauthorized local processes to retrieve geolocation information that should be protected.

The vulnerability requires local access to the device and some form of user interaction to exploit. This interaction requirement reduces the attack surface but does not eliminate the risk, particularly in scenarios involving malicious applications installed on the same device or physical access by an attacker.

When exploited, the attacker gains access to high-value confidential information (location data) while integrity and availability of the system remain unaffected. Location data can reveal sensitive information about user movements, home addresses, workplace locations, and daily routines.

Root Cause

The root cause of this vulnerability lies in insufficient access control enforcement within the Samsung Camera application. The application does not properly verify that requesting processes have the necessary permissions to access location metadata associated with captured photos or the camera's location services.

This type of improper access control typically occurs when:

• Permission checks are missing or inadequately implemented
• Intent filters are overly permissive
• Content providers expose sensitive data without proper access restrictions
• Inter-process communication mechanisms lack proper authentication

Attack Vector

The attack vector is local, meaning an attacker must have some level of access to the target device. The exploitation scenario typically involves:

1. A malicious application installed on the same device as the vulnerable Samsung Camera app
2. The malicious app exploits the improper access control to query or intercept location data
3. User interaction triggers the vulnerable code path, enabling the data leak
4. Location data is exfiltrated to the attacker

Since no verified proof-of-concept code is publicly available, the specific exploitation technique involves abusing Android's inter-process communication mechanisms or improper content provider configurations to access location data that should be restricted to the Camera application and authorized system components.

Detection Methods for CVE-2026-21014

Indicators of Compromise

• Unusual application behavior involving location data access from non-system applications
• Third-party applications requesting or accessing camera-related content providers
• Unexpected inter-process communication between the Samsung Camera app and unknown applications
• Log entries indicating unauthorized access attempts to camera location data

Detection Strategies

• Monitor Android system logs for unauthorized access attempts to Samsung Camera data providers
• Implement application-level monitoring to detect anomalous IPC (Inter-Process Communication) patterns
• Use mobile threat defense solutions to identify applications attempting to exploit access control weaknesses
• Review installed applications for suspicious permission requests related to location and storage access

Monitoring Recommendations

• Enable verbose logging on mobile device management (MDM) solutions to capture application interaction events
• Deploy SentinelOne Mobile Threat Defense to detect exploitation attempts and unauthorized data access
• Regularly audit installed applications and their permission usage patterns
• Monitor for applications exhibiting unusual location data query behavior

How to Mitigate CVE-2026-21014

Immediate Actions Required

• Update Samsung Camera to version 16.5.00.28 or later immediately
• Review and restrict permissions for installed third-party applications
• Enable application sandboxing and security features available on Samsung devices
• Audit device for potentially malicious applications that could exploit this vulnerability

Patch Information

Samsung has released a security update addressing this vulnerability. Users should update their Samsung Camera application to version 16.5.00.28 or later through the Galaxy Store or Samsung's official update channels.

For detailed patch information, refer to the Samsung Mobile Security Update advisory for April 2026.

Workarounds

• Temporarily disable location tagging in Samsung Camera settings until the patch can be applied
• Limit installation of applications from untrusted sources to reduce local attack surface
• Enable Samsung's Secure Folder to isolate sensitive applications
• Review and revoke unnecessary permissions from installed applications

# Check current Samsung Camera version via ADB
adb shell dumpsys package com.sec.android.app.camera | grep versionName

# Verify the installed version is 16.5.00.28 or later
# If vulnerable, update through Galaxy Store or Samsung Smart Switch
