CVE-2026-20663

Installed-app enumeration via unsanitized LaunchServices logging

Published Feb 11, 2026 · Updated Feb 11, 2026

Information disclosure in LaunchServices in Apple iOS and iPadOS allows local users to enumerate installed apps through an app. LaunchServices places installed-app information in logs without sufficient sanitization, making the inventory observable to an app. Affected branches are before 18.7.5 and before 26.3; app execution is required, and the reported consequence is inventory disclosure only.
