CVE-2025-31191

Root

Cause

CVE-2025-31191 is a vulnerability affecting Apple operating systems, including iOS, iPadOS, macOS, tvOS, and watchOS. The core issue is described as a logging problem where sensitive user data was not properly redacted from system logs. Apple addressed this with improved data redaction, indicating that the flaw allowed the logging subsystem to inadvertently record private information in a way that could be retrieved by other processes [1][3].

Exploitation

An attacker would need to have a malicious app installed on the device to exploit this vulnerability. The app could then access the system logs and extract the unredacted sensitive user data. No special network position or additional privileges beyond running a normal user-level app are required, making it a local attack vector that depends on social engineering or other means to get the app onto the target device [1].

Impact

Successful exploitation leads to unauthorized access to sensitive user data. The exact type of data is not specified in the advisory, but given the context of logging, it could include personal information, credentials, or other private data that the system logs during normal operation. Apple rates the severity as Medium (CVSS v3 base score 5.5), reflecting the need for local app access and the potential for information disclosure [1][3].

Mitigation

Apple released fixes on March 31, 2025, in iOS 18.4, iPadOS 18.4, macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5, tvOS 18.4, and watchOS 11.4 [1][2][3][4]. Users are strongly advised to update their devices to these versions to protect against exploitation.
