CVE-2025-24217 is a vulnerability identified in Apple’s iOS and iPadOS platforms, where an application may gain unauthorized access to sensitive user data. The root cause is insufficient redaction of sensitive information, allowing apps with limited privileges (local access with some privileges) to read data that should be protected. This issue affects multiple Apple operating systems, including iOS, iPadOS, macOS Sequoia, tvOS, and watchOS, with fixes released in version 18.4 for iOS/iPadOS and corresponding updates for other platforms. The vulnerability is categorized under CWE-200 (Exposure of Sensitive Information). The CVSS v3.1 base score is 5.5 (medium severity), with vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, indicating a local attack vector, low attack complexity, requiring privileges but no user interaction, and high impact on confidentiality only. No known exploits have been reported in the wild, suggesting limited active exploitation currently. The vulnerability could allow malicious or compromised apps to access sensitive user data such as personal information, credentials, or other protected content, potentially leading to privacy breaches or targeted attacks. The issue was mitigated by improving the redaction mechanisms to ensure sensitive data is properly obscured or inaccessible to unauthorized apps.

The primary impact of CVE-2025-24217 is the unauthorized disclosure of sensitive user data on affected Apple devices. This can lead to privacy violations, identity theft, or targeted phishing and social engineering attacks if sensitive information such as credentials, personal identifiers, or confidential communications are exposed. Since the vulnerability requires local access with some privileges, the risk is higher in environments where users install untrusted or malicious apps or where devices are physically accessible to attackers. Enterprises relying on iOS and iPadOS devices for sensitive communications or data processing could face compliance and reputational risks if user data is exposed. Although the vulnerability does not affect data integrity or system availability, the confidentiality breach alone can have significant consequences, especially in regulated industries or high-security environments. The lack of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation, particularly as attackers develop techniques to escalate privileges or bypass controls. Organizations with large deployments of Apple devices are at higher risk, especially if devices are not promptly updated to the patched versions.

To mitigate CVE-2025-24217, organizations and users should promptly update all affected Apple devices to iOS 18.4, iPadOS 18.4, macOS Sequoia 15.4, tvOS 18.4, and watchOS 11.4 or later versions containing the fix. Beyond patching, organizations should enforce strict app vetting policies, limiting installation to trusted sources and using Mobile Device Management (MDM) solutions to control app permissions and monitor device compliance. Employing least privilege principles for app permissions can reduce the risk of sensitive data exposure. Regular audits of installed applications and their permissions can help identify potentially risky apps. For high-security environments, consider restricting local device access and implementing endpoint security solutions that detect anomalous app behavior. User education on the risks of installing untrusted apps and the importance of timely updates is also critical. Monitoring for unusual data access patterns on devices may help detect exploitation attempts. Finally, organizations should maintain an inventory of Apple devices and ensure patch management processes include these updates.
