CVE-2025-32328 is a vulnerability identified in Google Android versions 13, 14, and 15, specifically within multiple functions of the Session.java file. The root cause is a logic error that allows a user on the device to access images belonging to other users without proper authorization checks. This results in a local elevation of privilege, where an attacker with local access can bypass user boundaries and view private images from other user profiles on the same device. Notably, exploitation does not require any additional execution privileges or user interaction, making it easier for an attacker with local access to leverage this flaw stealthily. The vulnerability affects multi-user Android environments, which are common in shared devices used in enterprise or family settings. Although no public exploits have been reported yet, the flaw poses a significant confidentiality risk by exposing sensitive image data across user accounts. The absence of a CVSS score suggests that the vulnerability is newly disclosed, and patches have not yet been published by Google. The flaw highlights the importance of robust user session management and access control in multi-user operating systems like Android. Organizations relying on Android devices for sensitive operations should be aware of this risk and prepare to deploy fixes promptly once available.

The primary impact of CVE-2025-32328 is the unauthorized disclosure of private images across different user accounts on the same Android device, compromising confidentiality. For European organizations, this could lead to privacy violations, especially in sectors handling sensitive personal or corporate data such as healthcare, finance, and government. The vulnerability could facilitate insider threats or malicious local users gaining access to data they should not see, undermining trust in device security. In shared device scenarios, such as kiosks, call centers, or mobile workforce devices, this flaw could expose sensitive information to unauthorized personnel. Although the vulnerability does not directly affect system integrity or availability, the breach of confidentiality can have regulatory and reputational consequences under GDPR and other privacy laws prevalent in Europe. The lack of required user interaction or additional privileges lowers the barrier for exploitation, increasing the risk in environments where devices are shared or physically accessible by multiple users.

1. Monitor Google’s official security advisories and apply patches immediately once they are released for Android versions 13, 14, and 15. 2. Enforce strict device usage policies limiting multi-user access on sensitive devices, or disable multi-user functionality where feasible. 3. Implement mobile device management (MDM) solutions to control user profiles and restrict unauthorized access to user data. 4. Conduct regular audits of device user accounts and access logs to detect anomalous access patterns to images or other sensitive files. 5. Educate users and administrators about the risks of shared device usage and encourage secure handling of devices with multiple user profiles. 6. Consider encrypting sensitive data at rest with user-specific keys to add an additional layer of protection against cross-user data access. 7. For enterprise deployments, segregate sensitive workloads onto dedicated devices or containers that do not share user sessions. 8. Limit physical access to devices to trusted personnel to reduce the risk of local exploitation.
