CVE-2025-46276 is an information disclosure vulnerability identified in Apple’s iOS and iPadOS platforms, as well as other Apple operating systems including macOS Sequoia, Sonoma, Tahoe, visionOS, and watchOS. The vulnerability arises from insufficient privacy controls that could allow a locally installed app with limited privileges (PR:L) to access sensitive user data without requiring user interaction (UI:N). The flaw does not impact system integrity or availability but compromises confidentiality by exposing potentially sensitive information. Apple addressed this issue by improving privacy controls in the affected operating systems, releasing patches in iOS 18.7.3, iPadOS 18.7.3, macOS 15.7.3, 14.8.3, 26.2 versions, visionOS 26.2, and watchOS 26.2. The CVSS v3.1 base score is 3.3, reflecting low severity due to the requirement for local access and privileges, and no need for user interaction. No known exploits have been reported in the wild, indicating limited active threat. The vulnerability affects a broad range of Apple devices, including iPhones, iPads, Macs, Apple Watches, and visionOS devices, making it relevant to a wide user base. The root cause is related to privacy control mechanisms that failed to adequately restrict app access to sensitive data, which Apple has now rectified through software updates.

The primary impact of CVE-2025-46276 is the potential unauthorized disclosure of sensitive user data by a locally installed app with limited privileges. While the vulnerability does not allow modification or destruction of data, nor does it affect system availability, the confidentiality breach could lead to privacy violations, exposure of personal or corporate information, and potential secondary attacks if sensitive data is leveraged. For organizations, especially those handling sensitive or regulated data on Apple devices, this vulnerability could increase the risk of insider threats or malicious apps exploiting the flaw to gather confidential information. However, the requirement for local privileges and absence of user interaction reduces the likelihood of widespread exploitation. The lack of known exploits in the wild further limits immediate risk. Nonetheless, environments with high security requirements, such as government, finance, healthcare, and enterprises with Apple device fleets, should consider the impact significant enough to warrant prompt patching.

To mitigate CVE-2025-46276, organizations and users should promptly apply the security updates released by Apple for iOS 18.7.3, iPadOS 18.7.3, macOS Sequoia 15.7.3, macOS Sonoma 14.8.3, macOS Tahoe 26.2, visionOS 26.2, and watchOS 26.2. Beyond patching, organizations should enforce strict app installation policies, limiting installation to trusted sources such as the Apple App Store and employing Mobile Device Management (MDM) solutions to control app permissions and monitor installed applications. Regular audits of installed apps and their permissions can help detect unauthorized or suspicious apps that might attempt to exploit this vulnerability. Additionally, implementing endpoint protection solutions that monitor for unusual app behavior can provide an additional layer of defense. User education on the risks of installing untrusted apps and the importance of timely updates is also critical. For highly sensitive environments, consider restricting local user privileges further and employing data loss prevention (DLP) tools to monitor sensitive data access.
