CVE-2025-26450 is a local elevation of privilege vulnerability affecting Google Android versions 13, 14, and 15. The flaw exists in the onInputEvent method of the IInputMethodSessionWrapper.java component, which is part of the Android Input Method Framework responsible for handling input events such as key presses and motion events. Due to a missing permission check, an untrusted application can inject arbitrary key and motion events into the default Input Method Editor (IME) without requiring any additional execution privileges or user interaction. This means a malicious app installed on the device can manipulate input events to escalate its privileges locally, potentially gaining unauthorized access to sensitive system functions or data. Since exploitation does not require user interaction, the vulnerability can be triggered silently once the malicious app is present on the device. No known exploits are currently reported in the wild, but the vulnerability is publicly disclosed and affects multiple recent Android versions, making it a significant risk for devices running these OS versions. The lack of a CVSS score indicates that the severity assessment must be based on the technical details, which suggest a high-impact flaw due to the ability to bypass security boundaries without user involvement or additional privileges.

For European organizations, this vulnerability poses a substantial risk, especially for enterprises relying on Android devices for business operations, secure communications, or access to corporate resources. An attacker exploiting this flaw could elevate privileges on affected devices, potentially leading to unauthorized access to confidential information, interception or manipulation of user input, and compromise of device integrity. This could facilitate further attacks such as data exfiltration, installation of persistent malware, or lateral movement within corporate networks. The silent nature of the exploit (no user interaction needed) increases the risk of undetected compromise. Organizations in sectors with high regulatory requirements for data protection, such as finance, healthcare, and government, could face severe compliance and reputational consequences if devices are compromised. Additionally, the widespread use of Android in mobile workforces across Europe amplifies the potential impact.

To mitigate this vulnerability, European organizations should prioritize the following actions: 1) Ensure all Android devices are updated to patched versions once Google releases security updates addressing CVE-2025-26450. 2) Implement strict application vetting policies to prevent installation of untrusted or potentially malicious apps, including the use of enterprise mobility management (EMM) solutions that enforce app whitelisting and restrict sideloading. 3) Monitor device behavior for unusual input event patterns or privilege escalations using mobile threat defense tools. 4) Educate users about the risks of installing apps from untrusted sources and encourage adherence to corporate app usage policies. 5) For highly sensitive environments, consider restricting the use of Android devices or isolating them from critical network segments until patches are applied. 6) Collaborate with device manufacturers and service providers to ensure timely deployment of security updates. These measures go beyond generic advice by focusing on proactive device management, behavioral monitoring, and user education tailored to the specific nature of this input event injection vulnerability.
