CVE-2025-26454 is a vulnerability identified in the Android operating system, specifically in versions 13, 14, and 15. The flaw exists in the validateUriSchemeAndPermission method of the DisclaimersParserImpl.java component. This method improperly handles authorization checks, leading to a confused deputy problem where a process with limited privileges can trick the system into granting access to data belonging to other users on the same device. The vulnerability allows a local attacker with limited privileges to escalate their access rights without requiring additional execution privileges or any user interaction, making exploitation straightforward once local access is obtained. The vulnerability affects confidentiality, integrity, and availability by enabling unauthorized data access and potential manipulation. It is classified under CWE-441, which relates to incorrect authorization. The CVSS v3.1 base score is 7.8, reflecting high severity due to the combination of local attack vector, low complexity, required privileges, and the absence of user interaction. No patches or exploits are currently publicly available, but the vulnerability poses a significant risk to Android devices until mitigated.

The impact of CVE-2025-26454 is substantial for organizations and individuals using affected Android versions. An attacker with local access can escalate privileges to access or modify data belonging to other users on the device, potentially exposing sensitive personal or corporate information. This can lead to data breaches, unauthorized data manipulation, and disruption of services relying on data integrity. In enterprise environments, compromised devices could serve as entry points for lateral movement or further attacks within corporate networks. The lack of required user interaction and the low complexity of exploitation increase the likelihood of successful attacks. Additionally, the vulnerability affects confidentiality, integrity, and availability, making it a comprehensive threat to device security and user privacy.

To mitigate CVE-2025-26454, organizations and users should: 1) Monitor for official security updates from Google and apply patches promptly once released for Android versions 13, 14, and 15. 2) Restrict local access to devices by enforcing strong device authentication and limiting physical or remote access to trusted users only. 3) Employ mobile device management (MDM) solutions to enforce security policies and monitor for suspicious activities indicative of privilege escalation attempts. 4) Use application sandboxing and permission controls to minimize the risk of unauthorized data access by limiting app privileges. 5) Conduct regular security audits and vulnerability assessments on Android devices within the organization to detect potential exploitation attempts. 6) Educate users about the risks of installing untrusted applications or granting unnecessary permissions that could facilitate local attacks. 7) Consider deploying endpoint detection and response (EDR) tools capable of identifying anomalous local privilege escalation behaviors on mobile devices.
