CVE-2026-84527

Improper Log Redaction Exposes Sensitive User Data

Published Sep 14, 2026 CVSS 3.1 · 5.5 Medium EPSS < 1% KEV · Not listed

Description

A logging issue was addressed with improved data redaction. This issue is fixed in iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, watchOS 27. An app may be able to access sensitive user data.

Analysis

Technical impact

A logging flaw that prevented proper redaction of user data was identified. An application can read credentials, personal identifiers, or other confidential data from system logs, effectively exposing sensitive information.

Affected Systems

Apple iOS, iPadOS, macOS, tvOS, visionOS, and watchOS are all affected. Fixed versions include iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, and watchOS 27. Devices running earlier releases remain vulnerable.

Risk and Exploitability

The CVSS score of 5.5 indicates moderate severity, and the EPSS score of less than 1% suggests a low probability of exploitation. The vulnerability is not listed in the CISA KEV catalog. Attackers would need local access to an application capable of reading system logs; once logged data is accessed, the application can read sensitive user information that was not properly redacted. Because the exploitation requires an existing app with sufficient permissions, the overall risk is moderate, but any device running an earlier release should apply the patch to eliminate the exposure.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade all affected Apple devices to the OS releases that contain the fix, such as iOS 27, macOS 27, and the corresponding versions for iPadOS, tvOS, visionOS, and watchOS.
If a device update cannot be performed immediately, apply device‑management policies that block or limit third‑party application access to system logs and enforce strict redaction rules for any user data logged.
Review or update your applications to guarantee that they do not write unredacted sensitive data to system logs; enable any built‑in log redaction features and clear existing logs to remove exposed information.
