CVE-2025-0086 is a security vulnerability identified in the Google Android operating system, specifically affecting versions 12, 12L, 13, 14, and 15. The flaw exists in the AccountManagerService.java component, within the onResult method. The vulnerability arises due to a missing permission check that allows an attacker to overwrite an authentication token. This flaw can lead to local information disclosure without requiring any additional execution privileges or user interaction. Essentially, a local attacker or malicious app with limited permissions could exploit this vulnerability to access sensitive authentication tokens, which are critical for user identity and session management. Since the vulnerability does not require user interaction and can be triggered locally, it increases the risk of stealthy exploitation. The absence of a CVSS score indicates that the vulnerability has not yet been fully evaluated for severity, but the technical details suggest a significant risk to confidentiality. No known exploits are currently reported in the wild, and no patches or mitigation links have been published at the time of this analysis. The vulnerability's impact is primarily on information disclosure, potentially allowing unauthorized access to sensitive user credentials or tokens, which could be leveraged for further attacks or privilege escalation.

For European organizations, this vulnerability poses a notable risk, especially for enterprises and government entities that rely heavily on Android devices for secure communications and authentication. The ability to overwrite authentication tokens locally could lead to unauthorized access to corporate accounts, email, and other sensitive services accessed via Android devices. This could compromise confidentiality of sensitive information, potentially leading to data breaches or unauthorized access to internal systems. Since Android devices are widely used across Europe in both personal and professional contexts, the risk extends to any organization with employees using vulnerable Android versions. The lack of required user interaction means that exploitation could occur silently, increasing the risk of undetected compromise. Furthermore, sectors such as finance, healthcare, and public administration, which handle sensitive personal and financial data, could face significant regulatory and reputational consequences if this vulnerability is exploited. The absence of known exploits in the wild provides a window for proactive mitigation, but organizations should act swiftly to reduce exposure.

European organizations should implement a multi-layered mitigation strategy. First, they should prioritize updating Android devices to the latest available versions once Google releases patches addressing CVE-2025-0086. Until patches are available, organizations should enforce strict app installation policies, limiting installations to trusted sources and employing mobile device management (MDM) solutions to monitor and control app permissions, especially those related to account management and authentication tokens. Employing runtime application self-protection (RASP) or endpoint detection and response (EDR) tools on Android devices can help detect anomalous behavior indicative of token manipulation. Additionally, organizations should educate users about the risks of installing untrusted applications and encourage the use of strong device-level security controls such as biometric authentication and device encryption. Regular audits of device security posture and token usage can help identify potential exploitation attempts. Finally, organizations should monitor threat intelligence feeds for updates on exploits and patches related to this vulnerability to respond promptly.
