CVE-2026-0024: Google Android Information Disclosure Flaw

CVE-2026-0024 Overview

A missing authorization vulnerability has been identified in Google Android's MediaProvider component, specifically within the isRedactionNeededForOpenViaContentResolver function of MediaProvider.java. This flaw enables local information disclosure by allowing unauthorized access to media location data without proper permission validation. The vulnerability can be exploited without requiring any user interaction or additional execution privileges.

Critical Impact

Local information disclosure allowing unauthorized revelation of media file location metadata on Android devices running versions 14.0 through 16.0 (including QPR2 beta releases).

Affected Products

• Google Android 14.0
• Google Android 15.0
• Google Android 16.0 (including QPR2 Beta 1, Beta 2, and Beta 3)

Discovery Timeline

• 2026-03-02 - CVE-2026-0024 published to NVD

Technical Details for CVE-2026-0024

Vulnerability Analysis

This vulnerability (CWE-862: Missing Authorization) affects Android's MediaProvider, a core system component responsible for managing media files and their metadata across the device. The isRedactionNeededForOpenViaContentResolver function is designed to determine whether sensitive location data embedded in media files should be redacted before being shared with requesting applications.

When applications access media files through the ContentResolver interface, this function should verify that the requesting application has appropriate permissions (such as ACCESS_MEDIA_LOCATION) before exposing geolocation metadata. However, due to a missing permission check in the implementation, the function fails to properly validate authorization, allowing any local application to access location data from media files without the necessary permissions.

This type of information disclosure is particularly concerning on mobile devices where photos and videos often contain precise GPS coordinates that could reveal sensitive user information such as home address, workplace location, or frequently visited locations.

Root Cause

The root cause is a missing authorization check in the isRedactionNeededForOpenViaContentResolver method within MediaProvider.java. The function does not properly verify that the calling application has the ACCESS_MEDIA_LOCATION permission before determining whether location redaction is needed. This allows applications without the proper permission to bypass the location redaction mechanism and access embedded geolocation data from media files accessed via ContentResolver.

Attack Vector

The attack is executed locally on the device and requires no user interaction. A malicious application installed on the device can exploit this vulnerability by:

1. Requesting access to media files through Android's ContentResolver API
2. Exploiting the missing permission check in isRedactionNeededForOpenViaContentResolver
3. Extracting location metadata (GPS coordinates) from photos and videos without having declared or been granted the ACCESS_MEDIA_LOCATION permission
4. Aggregating location data to build a profile of the user's movements and frequently visited locations

The vulnerability does not require the malicious application to have elevated privileges, making it particularly accessible to potential attackers.

Detection Methods for CVE-2026-0024

Indicators of Compromise

• Unusual media file access patterns from applications that should not require location metadata
• Applications accessing media files through ContentResolver without having declared ACCESS_MEDIA_LOCATION permission in their manifest
• Unexpected network transmissions containing GPS coordinate data from installed applications
• Anomalous permission bypass behavior logged in system security events

Detection Strategies

• Monitor ContentResolver access patterns for media files, particularly from applications without appropriate location permissions
• Implement runtime permission auditing to detect applications attempting to access location data from media without proper authorization
• Deploy mobile threat detection solutions capable of identifying permission bypass attempts on Android devices

Monitoring Recommendations

• Enable enhanced audit logging for MediaProvider operations where available
• Use enterprise mobile device management (MDM) solutions to monitor for suspicious application behavior
• Review installed applications for suspicious permission patterns or behaviors indicating potential exploitation

How to Mitigate CVE-2026-0024

Immediate Actions Required

• Apply the March 2026 Android security patch as soon as it becomes available for your device
• Review installed applications and remove any untrusted or unnecessary apps that may exploit this vulnerability
• Consider disabling location embedding in camera settings as a temporary mitigation
• Deploy enterprise MDM policies to restrict application installation from untrusted sources

Patch Information

Google has addressed this vulnerability in the Android Security Bulletin March 2026. Device manufacturers and carriers will distribute patches according to their standard update schedules. Users should check for and apply system updates as soon as they become available for their specific device.

For enterprise deployments, coordinate with your mobile device management provider to prioritize the deployment of the March 2026 security patch level across managed Android devices.

Workarounds

• Disable automatic geotagging in camera applications to prevent new media from containing location metadata
• Use third-party tools to strip EXIF location data from existing photos and videos on the device
• Restrict application installation to trusted sources only (Google Play Store with Play Protect enabled)
• Consider temporary use of Android's "Remove location before sharing" feature for sensitive media files until the patch is applied
