CVE-2025-26427 is a local privilege escalation vulnerability affecting Google Android versions 13 and 14. The vulnerability arises from a path traversal error in multiple locations within the Android system, specifically related to access control over the Android/data directory. Path traversal vulnerabilities allow an attacker to manipulate file paths to access directories and files outside the intended scope. In this case, the flaw permits unauthorized access to Android/data, which is typically sandboxed to protect app data. Exploiting this vulnerability enables an attacker to escalate privileges locally without requiring additional execution privileges beyond those already granted to the user. However, exploitation requires user interaction, meaning the attacker must trick the user into performing some action, such as opening a malicious file or app. No known exploits are currently observed in the wild, and no official patches or CVSS scores have been published at the time of this report. The vulnerability is significant because it undermines Android's sandboxing and access control mechanisms, potentially allowing malicious apps or local users to gain elevated privileges and access sensitive data or system functions that should be restricted. This could lead to further compromise of the device's security posture if leveraged in conjunction with other vulnerabilities or malware.

For European organizations, the impact of CVE-2025-26427 could be substantial, especially for enterprises relying on Android devices for business operations, including BYOD (Bring Your Own Device) environments. Successful exploitation could allow attackers to bypass security controls, access sensitive corporate data stored on devices, or install persistent malware with elevated privileges. This could lead to data breaches, intellectual property theft, or disruption of business processes. The requirement for user interaction somewhat limits the risk to targeted attacks rather than widespread automated exploitation. However, social engineering campaigns could be used to trick employees into triggering the vulnerability. Given the widespread use of Android devices across Europe in both consumer and enterprise contexts, the vulnerability poses a risk to sectors such as finance, healthcare, government, and critical infrastructure, where device security is paramount. Additionally, the lack of a patch at the time of disclosure means organizations must rely on mitigation strategies until updates are available.

1. Limit user interaction risks by educating employees about the dangers of opening untrusted files or apps, especially from unknown sources. 2. Enforce strict app installation policies, including the use of enterprise app stores and blocking installation from unknown sources. 3. Employ mobile device management (MDM) solutions to monitor device compliance and restrict risky behaviors. 4. Disable or restrict access to Android/data directories where feasible, or use file system permissions to limit exposure. 5. Monitor devices for unusual behavior indicative of privilege escalation attempts, such as unexpected access to protected directories or escalation of app privileges. 6. Apply security updates promptly once Google releases patches addressing this vulnerability. 7. Consider deploying endpoint detection and response (EDR) tools capable of detecting local privilege escalation attempts on Android devices. 8. For critical environments, consider restricting use of Android devices until patches are available or using alternative secure platforms.
