CVE-2025-30426 is a critical security vulnerability identified in Apple tvOS and other Apple operating systems including visionOS, iPadOS, iOS, and macOS Sequoia. The core issue involves an app's ability to enumerate the list of installed applications on a user's device without proper entitlement checks, violating expected access controls. This vulnerability is categorized under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The flaw allows any malicious app, without requiring privileges or user interaction, to remotely gather information about installed apps, which can be leveraged for profiling users, planning further targeted attacks, or bypassing security controls. The vulnerability affects multiple Apple platforms, with fixes implemented in visionOS 2.4, tvOS 18.4, iPadOS 17.7.6, iOS 18.4, and macOS Sequoia 15.4. The CVSS v3.1 base score is 9.8, indicating critical severity due to network attack vector, low attack complexity, no privileges required, and no user interaction needed. Although no known exploits are reported in the wild yet, the high severity and broad platform impact necessitate immediate attention. The vulnerability was addressed by Apple through additional entitlement checks to restrict unauthorized app enumeration capabilities.

For European organizations, this vulnerability poses significant privacy and security risks. Unauthorized enumeration of installed apps can reveal sensitive information about user behavior, installed security tools, or proprietary applications, enabling attackers to tailor subsequent attacks such as phishing, malware deployment, or lateral movement. In sectors like finance, healthcare, and government, where Apple devices are increasingly used, this could lead to data breaches or espionage. The ability to exploit this vulnerability remotely without user interaction or privileges increases the attack surface, potentially impacting large numbers of users and devices. Additionally, compromised devices could be used as footholds for broader network intrusion. The impact extends to consumer privacy and corporate security, undermining trust in Apple ecosystems within European markets.

European organizations should prioritize deploying the security updates released by Apple, including visionOS 2.4, tvOS 18.4, iPadOS 17.7.6, iOS 18.4, and macOS Sequoia 15.4, to ensure entitlement checks are enforced. Organizations should enforce strict app installation policies, limiting app sources to trusted vendors and using Mobile Device Management (MDM) solutions to control app permissions. Regular audits of installed applications and monitoring for unusual app enumeration activities can help detect exploitation attempts. Network segmentation and endpoint detection and response (EDR) tools should be employed to identify and contain suspicious behaviors. User education about the risks of installing untrusted apps and maintaining device software currency is essential. For high-security environments, consider restricting or disabling Apple TV and visionOS devices until patches are applied. Finally, coordinate with Apple support and security advisories for ongoing updates and threat intelligence.
