Sensitive information exposure in Apple system logging

IdentifiersCVE-2025-43423CWE-532· Insertion of Sensitive Information…

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.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows disclosure of sensitive user information via system logging. The impact is information exposure rather than code execution or privilege escalation. Apple specifically notes that an attacker with physical access to an unlocked device paired with a Mac may be able to view sensitive user information in system logging.

Mitigation

If you can’t patch tonight, do this now.

Until patching is completed, reduce opportunities for local log access by preventing unauthorized physical access, avoiding leaving devices unlocked, limiting use of paired-device workflows where not operationally necessary, and restricting access to Macs paired with affected devices. Because the issue depends on local physical access to an unlocked paired device, enforcing device locking and physical security materially reduces exposure.

Remediation

Patch, then assume compromise.

Upgrade affected systems to a fixed release: iOS 18.7.2 or later, iPadOS 18.7.2 or later, iOS 26.1 or later, iPadOS 26.1 or later, macOS Sequoia 15.7.2 or later, macOS Tahoe 26.1 or later, or visionOS 26.1 or later. Apple addressed the issue through improved data redaction in logging.
