The vulnerability is a permissions issue that allows an application to enumerate the list of apps installed on a device. This falls under CWE‑288 Unauthorized Access to Resource. Enumerating installed apps can expose sensitive usage patterns and potentially reveal personal data. The impact is primarily an information disclosure risk, compromising user privacy and potentially enabling targeted attacks by revealing installed software.

The issue affects multiple Apple operating systems: iOS, iPadOS, macOS, tvOS, visionOS, and watchOS. Versions prior to 26.1 are vulnerable, while the fix is delivered in iOS 26.1, iPadOS 26.1, macOS 26.1, tvOS 26.1, visionOS 26.1, and watchOS 26.1.

The CVSS score of 7.5 indicates a high severity, but the EPSS score of less than 1% shows a very low probability of exploitation. The vulnerability is not listed in the CISA KEV catalog. Attackers would need to run malicious or misconfigured apps on the device to leverage the enumeration vector, making the attack likely local and requiring device access. The risk is significant for environments that store sensitive data in installed applications and for users who value privacy.
