CVE-2025-32328 is a logic flaw vulnerability found in multiple functions of the Session.java component within Google Android operating system versions 13, 14, and 15. The flaw allows a local attacker to bypass user separation controls and access images belonging to other users on the same device. This is due to improper handling of user session data, leading to unauthorized access to private media files. The vulnerability does not require the attacker to have elevated privileges initially, nor does it require any user interaction, making it easier to exploit in environments where multiple users share a device or where local access is possible. The CVSS v3.1 base score is 7.8, indicating a high severity with significant impact on confidentiality, integrity, and availability. The attack vector is local, requiring low complexity and low privileges, but no user interaction. Although no exploits have been reported in the wild yet, the vulnerability poses a serious risk of data leakage and potential further privilege escalation on affected devices. The lack of patches at the time of publication necessitates immediate attention to mitigation strategies. This vulnerability is particularly concerning for environments where sensitive data is stored on shared Android devices, such as corporate or governmental settings.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive images and data stored on Android devices, compromising confidentiality. Integrity and availability could also be affected if the attacker leverages this access to escalate privileges further and manipulate or delete data. Organizations relying on Android devices for secure communications, data storage, or multi-user access scenarios face increased risk. The breach of privacy could lead to regulatory non-compliance under GDPR, resulting in legal and financial repercussions. The vulnerability's local attack vector means that physical or local network access is required, which may limit remote exploitation but increases risk in environments with shared devices or insufficient physical security. The potential for lateral movement within corporate networks exists if compromised devices are connected to internal systems. This threat is particularly critical for sectors handling sensitive personal or corporate data, such as finance, healthcare, and government agencies in Europe.

1. Apply official security patches from Google immediately once they become available for Android versions 13, 14, and 15. 2. Until patches are released, restrict physical and local access to Android devices, especially in multi-user environments. 3. Enforce strict device usage policies that limit the number of users per device and implement strong authentication controls. 4. Use mobile device management (MDM) solutions to monitor device behavior and detect anomalous access patterns to media files. 5. Educate users about the risks of sharing devices and encourage use of separate user profiles with minimal privileges. 6. Disable or limit access to shared media folders where feasible. 7. Regularly audit device logs for signs of unauthorized access attempts. 8. Consider deploying endpoint detection and response (EDR) tools capable of monitoring local privilege escalation attempts on Android devices. 9. Coordinate with IT security teams to ensure rapid incident response capabilities in case exploitation is detected.
