CVE-2025-43423 is a security vulnerability identified in Apple visionOS and related Apple operating systems including iOS, iPadOS, and macOS Sequoia. The root cause is a logging issue where sensitive user information is insufficiently redacted in system logs. This flaw allows an attacker who has physical access to an unlocked visionOS device that is paired with a Mac to view sensitive information that should otherwise be protected. The vulnerability arises because system logs, which are intended to aid in troubleshooting and system monitoring, inadvertently contain sensitive data due to inadequate data sanitization before logging. Apple addressed this issue by improving data redaction in system logging and released patches in iOS 26.1, iPadOS 26.1, macOS Sequoia 15.7.2, and visionOS 26.1. Exploitation requires the attacker to have physical access to the device and the device must be unlocked and paired with a Mac, which limits the attack surface to scenarios involving insider threats or physical theft. There are no reports of active exploitation in the wild as of the publication date. The vulnerability primarily impacts confidentiality, as sensitive user data could be exposed to unauthorized individuals. The lack of a CVSS score necessitates an assessment based on impact and exploit conditions. The vulnerability affects all versions prior to the patched releases. Organizations using Apple visionOS devices in environments where physical security cannot be guaranteed are at risk of sensitive data leakage through system logs.

The primary impact of CVE-2025-43423 is the potential exposure of sensitive user information through system logs on Apple visionOS devices paired with Macs. For European organizations, this could lead to confidentiality breaches, especially in sectors handling sensitive personal data, intellectual property, or classified information. The requirement for physical access and an unlocked device reduces the risk of remote exploitation but increases the threat from insider attacks, device theft, or loss. In environments such as corporate offices, research institutions, or government agencies where visionOS devices may be used, unauthorized access to sensitive logs could facilitate further attacks or data leakage. The exposure could undermine user privacy, violate data protection regulations such as GDPR, and damage organizational reputation. Additionally, if attackers extract credentials or other sensitive tokens from logs, they could escalate privileges or move laterally within networks. The impact on integrity and availability is minimal, as the vulnerability does not allow modification or disruption of system functions. However, the confidentiality impact is significant enough to warrant urgent remediation in sensitive environments.

1. Apply the official Apple patches immediately by upgrading to iOS 26.1, iPadOS 26.1, macOS Sequoia 15.7.2, and visionOS 26.1 or later versions to ensure improved data redaction in system logs. 2. Enforce strict physical security controls to prevent unauthorized physical access to devices, including secure storage and access policies. 3. Implement automatic device locking with short timeout intervals to minimize the window during which an unlocked device can be accessed. 4. Restrict pairing privileges between visionOS devices and Macs to trusted users only, and regularly audit paired devices. 5. Educate users about the risks of leaving devices unlocked and unattended, especially in shared or public spaces. 6. Monitor system logs and access logs for unusual activity that could indicate attempts to access sensitive information. 7. Consider disabling or limiting system logging where feasible in highly sensitive environments until patches are applied. 8. Integrate device management solutions that enforce compliance with security policies related to device locking and pairing. 9. Review and update incident response plans to include scenarios involving physical device compromise and sensitive data exposure via logs.
