CVE-2025-30454 is a vulnerability identified in Apple tvOS related to improper path handling due to insufficient validation of file paths within the operating system. This flaw allows a maliciously crafted application to potentially access private information stored on the device, violating confidentiality. The vulnerability is categorized under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). Exploitation requires the attacker to have local access to the device and to convince the user to interact with the malicious app, but does not require any special privileges or authentication. The CVSS v3.1 base score is 5.5 (medium severity), with vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N, indicating local attack vector, low complexity, no privileges required, user interaction needed, unchanged scope, high confidentiality impact, and no integrity or availability impact. Apple has addressed this issue in tvOS 18.4, macOS Sonoma 14.7.5, iOS 18.4, iPadOS 18.4, and macOS Sequoia 15.4, improving path validation to prevent unauthorized access. No known exploits have been reported in the wild as of the publication date. The vulnerability primarily threatens the confidentiality of private data on Apple TV devices, which may include user credentials, personal media, or other sensitive information accessible to apps. Given the nature of the flaw, exploitation is limited to scenarios where a malicious app is installed and executed, emphasizing the importance of app vetting and user caution.

For European organizations, the primary impact of CVE-2025-30454 is the potential unauthorized disclosure of sensitive information stored on Apple TV devices. This could include corporate media content, user credentials, or other private data accessible through installed apps. Sectors such as media, entertainment, education, and corporate environments using Apple TV for presentations or digital signage are particularly at risk. Confidentiality breaches could lead to data leaks, reputational damage, and compliance issues under GDPR if personal data is exposed. The requirement for local access and user interaction limits large-scale remote exploitation but does not eliminate insider threats or targeted attacks. Organizations with unmanaged or poorly controlled Apple TV deployments face higher risk. The vulnerability does not affect system integrity or availability, so operational disruption is unlikely. However, the exposure of private information could facilitate further attacks or espionage, especially in sensitive environments.

1. Immediately update all Apple TV devices to tvOS 18.4 or later to apply the security fix. 2. Enforce strict app installation policies, allowing only apps from trusted sources such as the Apple App Store. 3. Implement device management solutions to monitor and control app installations and permissions on Apple TV devices. 4. Educate users about the risks of installing untrusted apps and the importance of avoiding suspicious prompts requiring interaction. 5. Regularly audit Apple TV devices for unauthorized or suspicious applications. 6. Where feasible, restrict physical access to Apple TV devices to prevent local attackers from installing malicious apps. 7. Integrate Apple TV devices into broader endpoint security monitoring to detect anomalous behavior indicative of exploitation attempts. 8. Review and limit the amount of sensitive data accessible via Apple TV apps to minimize exposure in case of compromise.
