CVE-2025-48618 is a vulnerability identified in the Android operating system, specifically affecting versions 13, 14, 15, and 16. The flaw exists in the processLaunchBrowser method within CommandParamsFactory.java, where improper locking mechanisms allow browser interactions to be initiated directly from the device lockscreen. This improper locking means that an attacker with physical access to the device can trigger browser processes without needing to unlock the device or gain additional execution privileges. The vulnerability does not require any user interaction, making it easier to exploit if physical access is obtained. This can lead to an elevation of privilege, where an attacker could potentially bypass lockscreen protections and access sensitive device functions or data. Although no public exploits have been reported yet, the vulnerability poses a significant risk due to the widespread use of affected Android versions globally, including Europe. The lack of a CVSS score indicates that the vulnerability is newly published and may not yet have been fully assessed, but the technical details suggest a serious security concern. The vulnerability is categorized as an elevation of privilege, which can compromise device confidentiality and integrity by allowing unauthorized access from a locked state. The flaw stems from a software design issue in the locking mechanism of the browser launch process, highlighting the importance of secure state management in mobile OS components.

For European organizations, this vulnerability could have serious implications, especially for enterprises relying on Android devices for secure communications and data access. The ability to escalate privileges from the lockscreen without user interaction means that lost or stolen devices could be more easily compromised, potentially exposing sensitive corporate data or enabling unauthorized network access. This risk is heightened in sectors such as finance, government, and critical infrastructure, where device security is paramount. Additionally, the vulnerability could be exploited to bypass mobile device management (MDM) controls or endpoint security measures that rely on lockscreen protections. The impact extends to privacy concerns for individual users within organizations, as unauthorized browser interactions could lead to phishing or malware delivery. Given the physical access requirement, the threat is more relevant in environments where devices are at risk of theft or unauthorized physical access, such as public-facing roles or mobile workforces. The lack of known exploits currently limits immediate risk but does not diminish the potential for future attacks once exploit code becomes available.

Organizations should prioritize applying official patches from Google as soon as they are released for affected Android versions 13 through 16. Until patches are available, physical security controls should be enhanced to prevent unauthorized access to devices, including secure storage and use of device locks with strong authentication methods. Implementing device encryption and remote wipe capabilities can mitigate data exposure risks if a device is lost or stolen. Mobile Device Management (MDM) solutions should be configured to monitor for unusual lockscreen activity or unauthorized browser launches. User education on the risks of physical device compromise and prompt reporting of lost devices is critical. Additionally, organizations can consider restricting browser access from lockscreen states through custom policies or third-party security tools where feasible. Regular security audits and penetration testing focusing on mobile device security can help identify and address related vulnerabilities proactively. Monitoring threat intelligence feeds for emerging exploits related to CVE-2025-48618 will enable timely response to new attack vectors.
