CVE-2025-31242

Overview

CVE-2025-31242 is a privacy vulnerability in Apple's operating systems that stems from inadequate redaction of private data in log entries. The issue affects iOS, iPadOS, macOS, tvOS, visionOS, and watchOS, as confirmed by Apple's security advisories [1][2][3][4]. The root cause is that sensitive user information was not properly masked when written to system logs, potentially exposing it to any app with read access to those logs.

Exploitation

To exploit this vulnerability, an attacker would need to have an app installed on the affected device that is capable of reading system log entries. No special network position or elevated privileges are described as prerequisites beyond running a malicious or untrusted application. The attack surface is local, meaning the app must already be executing on the device [1][2].

Impact

A successful exploit allows the malicious app to access sensitive user data that should have been redacted from log output. This could include personal information, credentials, or other private data, depending on what the legitimate application logs. The severity is rated Medium (CVSS v3 base score 5.5), reflecting the need for an installed app but the potential for significant privacy exposure [2].

Mitigation

Apple has addressed CVE-2025-31242 in multiple operating system releases: iOS 18.5, iPadOS 18.5, iPadOS 17.7.7, macOS Sequoia 15.5, macOS Sonoma 14.7.6, macOS Ventura 13.7.6, tvOS 18.5, visionOS 2.5, and watchOS 11.5 [1][2]. Users are strongly advised to update their devices to the latest available versions to protect against this privacy issue.
