CVE-2025-30439 is a vulnerability identified in Apple iOS and iPadOS that allows an attacker with physical access to a locked device to view sensitive user information. This issue stems from insufficient access control checks that permitted unauthorized data exposure even when the device was locked. The vulnerability affects multiple Apple platforms, including iOS, iPadOS, macOS Sequoia, visionOS, and watchOS, and was resolved in their respective 18.4, 15.4, 2.4, and 11.4 updates. The CVSS 3.1 base score is 4.6, reflecting a medium severity level, with the vector indicating physical attack vector (AV:P), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). The vulnerability is classified under CWE-200 (Exposure of Sensitive Information). Exploitation does not require authentication or user interaction, making it a straightforward risk if physical access is gained. Although no known exploits are currently reported in the wild, the potential for sensitive data leakage on locked devices poses a significant privacy risk. Apple’s fix involves improved checks to prevent unauthorized data viewing when the device is locked.

The primary impact of CVE-2025-30439 is the unauthorized disclosure of sensitive user information from locked Apple devices. This compromises confidentiality, potentially exposing personal data, credentials, or other private information stored on the device. Since the vulnerability does not affect integrity or availability, the device’s functionality remains intact, but the privacy breach can lead to identity theft, targeted attacks, or further exploitation. Organizations that issue Apple devices to employees, especially those handling sensitive or regulated data, face increased risk of data leakage if devices are lost or stolen. The ease of exploitation with physical access and no need for user interaction heightens the threat in environments where physical device security is weak. Although no active exploitation is reported, the vulnerability could be leveraged by attackers with brief physical access, such as in theft, insider threats, or during device transport. This risk extends to individuals and enterprises relying heavily on Apple mobile ecosystems.

1. Immediately update all affected Apple devices to iOS 18.4, iPadOS 18.4, macOS Sequoia 15.4, visionOS 2.4, and watchOS 11.4 or later to apply the vendor’s fix. 2. Enforce strict physical security policies to prevent unauthorized access to devices, including secure storage, use of tamper-evident bags, and controlled access areas. 3. Implement device management solutions that enable remote wipe and lock capabilities to mitigate risks if a device is lost or stolen. 4. Educate users on the importance of reporting lost or stolen devices immediately. 5. Consider additional encryption or data protection layers for highly sensitive information beyond the device’s native protections. 6. Monitor for unusual access patterns or attempts to access devices physically in sensitive environments. 7. Regularly audit device compliance with patching and physical security policies. These measures collectively reduce the likelihood of successful exploitation and limit data exposure.
