CVE-2025-32329 is a logic error vulnerability found in multiple functions within the Session.java component of Google Android versions 13, 14, and 15. The flaw allows a local attacker to bypass user boundaries and access images belonging to other users on the same device. This occurs due to improper handling of user session data, which fails to enforce correct access controls between different user profiles on a shared device. The vulnerability does not require any additional execution privileges beyond those already granted to the attacker, nor does it require any user interaction, making it easier to exploit in multi-user environments. The CVSS v3.1 base score is 7.8, indicating a high severity level, with impacts rated as high on confidentiality, integrity, and availability. The attack vector is local, requiring the attacker to have some level of access to the device, but no elevated privileges are necessary initially. This vulnerability could allow attackers to escalate privileges locally, potentially leading to full device compromise or unauthorized data disclosure. No public exploits have been reported yet, but the flaw's nature suggests it could be leveraged in targeted attacks or by malicious insiders. The absence of patches at the time of publication means organizations must prepare to deploy updates promptly once available.

For European organizations, the impact of CVE-2025-32329 is significant, especially in environments where Android devices are shared among multiple users or used in enterprise settings with sensitive data. Unauthorized access to images and potentially other user data can lead to breaches of personal and corporate information, violating GDPR and other data protection regulations. The elevation of privilege can also enable attackers to install malicious software, manipulate device settings, or disrupt device availability, affecting operational continuity. This vulnerability undermines trust in Android device security, potentially impacting sectors such as finance, healthcare, and government, where data confidentiality and integrity are paramount. The local attack vector limits remote exploitation but does not eliminate risk, as insider threats or compromised devices could be leveraged. The lack of user interaction requirement increases the risk of stealthy exploitation. Overall, this vulnerability could result in data leakage, reputational damage, regulatory penalties, and increased incident response costs for European organizations.

To mitigate CVE-2025-32329, European organizations should: 1) Monitor Google’s security advisories closely and apply official patches immediately upon release to affected Android versions 13, 14, and 15. 2) Enforce strict device access controls, including strong authentication mechanisms and user separation policies, to limit local attacker opportunities. 3) Restrict multi-user device usage where possible, or implement device management policies that isolate user data effectively. 4) Employ Mobile Device Management (MDM) solutions to monitor device behavior and enforce security configurations. 5) Educate users about the risks of local privilege escalation and the importance of not installing untrusted applications or granting unnecessary permissions. 6) Conduct regular security audits and vulnerability assessments on Android devices in use. 7) Consider disabling or limiting features that allow multiple user profiles on devices used in sensitive environments until patches are applied. These steps go beyond generic advice by focusing on operational controls and proactive monitoring tailored to the vulnerability’s characteristics.
