CVE-2024-44194 is a vulnerability identified in Apple visionOS and related Apple operating systems that allows an application to access sensitive user data improperly. The root cause is insufficient redaction of sensitive information, which means that apps with certain privileges can bypass intended data protections and read confidential user data. This vulnerability affects visionOS prior to version 2.1, watchOS before 11.1, iOS before 18.1, and iPadOS before 18.1. The issue does not require user interaction but does require the app to have limited privileges (PR:L), indicating that the app must be installed and have some level of access but does not need elevated privileges. The attack vector is local (AV:L), meaning the attacker must have local access to the device, such as through an installed app. The vulnerability impacts confidentiality (C:H) but does not affect integrity or availability. Apple addressed this vulnerability by improving the redaction mechanisms that prevent sensitive data leakage. No known exploits are currently reported in the wild, but the vulnerability poses a risk of unauthorized data disclosure if exploited. The CVSS 3.1 base score is 5.5, categorizing it as medium severity. This vulnerability is particularly relevant for users and organizations deploying Apple visionOS devices, especially in environments where sensitive data confidentiality is critical.

For European organizations, the primary impact of CVE-2024-44194 is the potential unauthorized disclosure of sensitive user data on Apple visionOS devices. This could lead to privacy violations, leakage of confidential corporate or personal information, and potential compliance issues under regulations such as GDPR. Since the vulnerability requires local access and limited privileges, the risk is higher in environments where users can install untrusted apps or where devices are shared or less controlled. The confidentiality breach could undermine trust in Apple visionOS devices used in corporate settings, particularly in sectors handling sensitive data like finance, healthcare, and government. Although the vulnerability does not affect system integrity or availability, the exposure of sensitive data could facilitate further attacks or social engineering. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time. Organizations relying on Apple visionOS for augmented or mixed reality applications should prioritize patching to maintain data confidentiality and regulatory compliance.

European organizations should immediately update all affected Apple devices to watchOS 11.1, visionOS 2.1, iOS 18.1, and iPadOS 18.1 or later to apply the fix for CVE-2024-44194. Beyond patching, organizations should enforce strict app installation policies, allowing only trusted and vetted applications to reduce the risk of malicious apps exploiting this vulnerability. Implement Mobile Device Management (MDM) solutions to control app permissions and monitor device compliance. Educate users about the risks of installing unverified apps and the importance of keeping devices updated. For environments with highly sensitive data, consider additional endpoint protection that can detect anomalous app behavior. Regularly audit device configurations and app permissions to ensure minimal privilege principles are enforced. Finally, monitor security advisories from Apple for any updates or emerging exploit information related to this vulnerability.
