CVE-2025-32326 is a vulnerability identified in Google Android operating system versions 13, 14, 15, and 16. The flaw exists in multiple functions within the AppRestrictionsFragment.java component, where a confused deputy problem allows an attacker to bypass intent security checks. This confused deputy vulnerability means that the system component improperly trusts an intent, enabling an attacker with local access to escalate privileges without needing additional execution rights. The attack vector is local, requiring user interaction, such as tricking the user into performing an action that triggers the malicious intent. The vulnerability affects the confidentiality, integrity, and availability of the device, as it allows an attacker to gain elevated privileges potentially leading to full device compromise. The CVSS v3.1 base score is 7.8, indicating high severity, with metrics AV:L (local attack vector), AC:L (low attack complexity), PR:L (low privileges required), UI:N (no user interaction needed for the attack itself, but user interaction is needed to initiate), and full impact on confidentiality, integrity, and availability. Although no public exploits are known at this time, the vulnerability's nature and affected Android versions make it a significant risk. The CWE associated is CWE-441 (Incorrect Authorization), highlighting the improper validation of intent permissions. No patches are currently linked, so mitigation relies on defensive controls until updates are released.

The vulnerability allows an attacker with local access to escalate privileges on affected Android devices, potentially gaining full control over the device. This can lead to unauthorized access to sensitive data, modification or deletion of critical system files, and disruption of device functionality. For organizations, this could mean compromised employee devices, leading to data breaches, lateral movement within corporate networks, and undermining of mobile device management controls. The requirement for user interaction limits remote exploitation but does not eliminate risk, especially in environments where social engineering or malicious apps can induce the necessary user actions. The broad range of affected Android versions means a large population of devices is vulnerable, increasing the potential attack surface. The absence of known exploits in the wild currently reduces immediate risk but also means defenders must be proactive. The impact on confidentiality, integrity, and availability is high, making this a critical concern for both individual users and enterprises relying on Android devices for secure communications and operations.

Until official patches are released, organizations and users should implement strict app permission policies, restricting installation of untrusted applications and limiting the ability of apps to send or receive intents that could trigger this vulnerability. Employ mobile device management (MDM) solutions to enforce security policies and monitor for suspicious app behavior or privilege escalations. Educate users about the risks of interacting with untrusted prompts or applications that request unusual permissions or actions. Disable or restrict features related to AppRestrictionsFragment where possible, or apply custom security policies to limit intent handling. Regularly monitor security advisories from Google for patch releases and apply updates promptly. Conduct internal security assessments and penetration testing focusing on local privilege escalation vectors to identify potential exploitation paths. Consider deploying endpoint detection and response (EDR) tools capable of detecting anomalous privilege escalation attempts on mobile devices.
