CVE-2025-26430 is a high-severity elevation of privilege vulnerability identified in Google Android version 15. The flaw exists in the getDestinationForApp function of the SpaAppBridgeActivity component, where a logic error leads to a cross-user file reveal. This vulnerability allows a local attacker to escalate privileges without requiring additional execution privileges or user interaction. The core issue is a logic flaw that improperly restricts access controls, enabling an attacker with limited privileges to access or manipulate files belonging to other users on the same device. The vulnerability is classified under CWE-285 (Improper Authorization), indicating that the affected code does not correctly enforce access restrictions. The CVSS v3.1 base score is 7.8, reflecting high severity due to the combination of local attack vector (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits are reported in the wild yet, the vulnerability's characteristics make it a significant risk for local privilege escalation on affected Android devices. No patch links are currently provided, suggesting that mitigation may rely on vendor updates or workarounds once available.

For European organizations, this vulnerability poses a considerable risk, especially for enterprises and government agencies that rely on Android 15 devices for sensitive communications, mobile workforce operations, or secure data access. An attacker with local access—such as a malicious insider, a compromised device user, or through physical access—could exploit this flaw to gain elevated privileges, potentially accessing confidential data, installing persistent malware, or disrupting device functionality. This could lead to data breaches, loss of data integrity, and operational disruptions. The lack of required user interaction lowers the barrier for exploitation, increasing the threat level. Organizations with Bring Your Own Device (BYOD) policies or those issuing Android 15 devices to employees must be particularly vigilant. The vulnerability could also be leveraged in targeted attacks against high-value individuals or critical infrastructure operators within Europe, amplifying its impact.

European organizations should implement a multi-layered mitigation strategy: 1) Monitor vendor communications closely and apply official security patches from Google as soon as they become available. 2) Restrict physical and local access to Android 15 devices, enforcing strict device usage policies and employing mobile device management (MDM) solutions to control app installations and permissions. 3) Employ endpoint detection and response (EDR) tools capable of identifying suspicious local privilege escalation attempts. 4) Educate users about the risks of installing untrusted applications or granting unnecessary permissions. 5) Where possible, limit the number of users with local access privileges on devices and enforce strong authentication mechanisms to reduce the risk of unauthorized local exploitation. 6) Consider temporarily restricting the use of Android 15 devices in highly sensitive environments until patches are applied.
