CVE-2025-0083 is a vulnerability identified in multiple versions of the Google Android operating system, specifically versions 12, 12L, 13, 14, and 15. The core issue arises from improper handling of URI double encoding in multiple locations within the system. This flaw allows an attacker to bypass user profile isolation mechanisms by accessing content across different user profiles on the same device. The vulnerability leads to local information disclosure, meaning that sensitive data from other user profiles can be accessed without requiring elevated privileges or additional execution rights. Notably, exploitation does not require any user interaction, which increases the risk of automated or stealthy attacks. The vulnerability is local, so an attacker must have some level of access to the device, but no further authentication or user consent is needed to exploit the flaw. The absence of a CVSS score indicates that the vulnerability has not yet been fully assessed for severity, but the technical details suggest a significant privacy risk due to cross-profile data leakage. There are no known exploits in the wild at the time of publication, and no official patches have been linked yet, which may indicate that mitigation is still pending or in development.

For European organizations, the impact of CVE-2025-0083 can be substantial, especially for enterprises and government agencies that use Android devices with multiple user profiles or shared devices. The vulnerability could lead to unauthorized disclosure of sensitive information such as corporate emails, documents, or personal data stored in separate user profiles. This breach of confidentiality could violate GDPR requirements, leading to regulatory penalties and reputational damage. Additionally, sectors that rely on Android devices for secure communications or data access—such as healthcare, finance, and public administration—may face increased risks of data leakage. Since exploitation requires local access but no user interaction, insider threats or compromised devices could be leveraged to extract data from other profiles without detection. The lack of required privileges lowers the barrier for attackers who have physical or remote access to the device. Overall, this vulnerability undermines the security model of user profile isolation on Android, which is critical for multi-user environments common in enterprise and shared device scenarios.

To mitigate the risks posed by CVE-2025-0083, European organizations should take several specific steps beyond generic advice: 1) Immediately audit and restrict physical and logical access to Android devices, ensuring only trusted users can access devices with multiple profiles. 2) Deploy mobile device management (MDM) solutions that enforce strict user profile controls and monitor for unusual access patterns across profiles. 3) Encourage or enforce the use of single-user profiles where possible, especially on devices handling sensitive data, to reduce the attack surface. 4) Monitor Android security bulletins and apply patches promptly once Google releases fixes for this vulnerability. 5) Implement application-level encryption for sensitive data stored on devices to reduce the impact of any unauthorized access. 6) Educate users and administrators about the risks of profile sharing and the importance of device security hygiene. 7) Consider disabling or limiting the use of multiple user profiles on corporate devices until the vulnerability is fully addressed. These targeted measures will help contain the risk of cross-profile data leakage and protect sensitive information in multi-user Android environments.
