CVE-2025-31191 is a medium-severity vulnerability affecting Apple tvOS, as well as other Apple operating systems including macOS Ventura 13.7.5, macOS Sequoia 15.4, macOS Sonoma 14.7.5, iOS 18.4, and iPadOS 18.4. The vulnerability arises from improper state management within the tvOS platform that could allow a malicious or compromised app to access sensitive user data without proper authorization. Specifically, the flaw is categorized under CWE-200, which relates to exposure of sensitive information to unauthorized actors. The vulnerability does not require privileges (PR:N) but does require user interaction (UI:R), meaning that exploitation depends on a user running or interacting with a malicious app. The attack vector is local (AV:L), indicating that the attacker must have local access to the device, such as through app installation. The impact is primarily on confidentiality (C:H), with no direct impact on integrity or availability. The vulnerability has been addressed by Apple through improved state management and is fixed in the latest versions of the affected operating systems. No known exploits are currently in the wild. The CVSS v3.1 base score is 5.5, reflecting a medium severity level. This vulnerability highlights the risk of sensitive data leakage via apps on Apple TV devices and related platforms, emphasizing the importance of app vetting and timely patching.

For European organizations, especially those utilizing Apple TV devices in corporate environments or for digital signage, this vulnerability poses a risk of unauthorized disclosure of sensitive information. While the attack requires local access and user interaction, the potential leakage of confidential data could lead to privacy violations, intellectual property exposure, or leakage of internal communications. Organizations in sectors such as finance, healthcare, and government, where data confidentiality is paramount, could face compliance and reputational risks if sensitive data is exposed. Additionally, the integration of Apple devices in unified communication and collaboration environments means that compromised data could facilitate further attacks or social engineering. Although the vulnerability does not affect system integrity or availability, the confidentiality breach alone is significant, especially under stringent European data protection regulations like GDPR.

European organizations should ensure that all Apple devices, including Apple TVs, are updated promptly to the patched versions (tvOS 18.4 and the corresponding macOS and iOS versions). Device management policies should restrict installation of untrusted or unauthorized applications, leveraging Mobile Device Management (MDM) solutions to enforce app whitelisting and control user permissions. User training should emphasize the risks of installing unverified apps and the importance of applying updates. Network segmentation can limit local access to Apple TV devices, reducing the attack surface. Additionally, organizations should monitor device logs for unusual app behavior and consider disabling or restricting Apple TV usage in sensitive environments where possible. Regular security assessments should include Apple TV and related Apple devices to ensure compliance with security policies.
