Sensitive information exposure in Apple system logging
CVE-2025-43423 is an Apple logging/redaction vulnerability affecting iOS, iPadOS, macOS, and visionOS. Apple states that a logging issue was addressed with improved data redaction. Under the vulnerable condition, sensitive user information could be written to or exposed through system logs without sufficient redaction. The issue is described in the context of an unlocked device paired with a Mac, indicating that log data associated with the paired device could reveal sensitive information to someone able to access the device locally. Apple fixed the issue in iOS 18.7.2 and iPadOS 18.7.2, iOS 26.1 and iPadOS 26.1, macOS Sequoia 15.7.2, macOS Tahoe 26.1, and visionOS 26.1.
