CVE-2025-24202 is a vulnerability identified in Apple iOS and iPadOS operating systems, fixed in versions 18.4 and later. The root cause is a logging issue where sensitive user data is insufficiently redacted in system logs, potentially allowing an unprivileged app to access this sensitive information. The vulnerability is categorized under CWE-284, indicating an authorization issue. The CVSS v3.1 score is 5.5 (medium severity), with vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N, meaning the attack requires local access and user interaction but no privileges, and it impacts confidentiality significantly without affecting integrity or availability. The vulnerability could be exploited by a malicious app that tricks the user into interaction, thereby gaining access to sensitive data that should have been protected by proper log redaction. Apple resolved this by improving data redaction in logs in iOS 18.4, iPadOS 18.4, and macOS Sequoia 15.4. No public exploits have been reported, but the risk remains until devices are updated.

The vulnerability allows unauthorized apps to access sensitive user data, potentially leading to privacy breaches, identity theft, or leakage of confidential information. Since the flaw affects logging mechanisms, sensitive information that should not be exposed could be retrieved by malicious apps, compromising user confidentiality. Although the vulnerability does not affect system integrity or availability, the exposure of sensitive data can have serious consequences for individuals and organizations, especially those handling sensitive communications or proprietary information on iOS/iPadOS devices. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk, particularly in environments where users may install untrusted apps or be targeted by social engineering. Organizations relying heavily on Apple mobile devices for sensitive operations could face data leakage risks until patched.

1. Immediately update all affected Apple devices to iOS 18.4, iPadOS 18.4, or macOS Sequoia 15.4 or later to apply the patch that improves data redaction in logs. 2. Restrict installation of apps to trusted sources only, such as the Apple App Store, and enforce mobile device management (MDM) policies to control app permissions and installations. 3. Educate users about the risks of installing untrusted apps and the importance of avoiding suspicious links or prompts that require interaction. 4. Monitor device logs and app behaviors for unusual access patterns or attempts to read sensitive data. 5. Employ endpoint security solutions capable of detecting anomalous app activities on iOS/iPadOS devices. 6. For organizations, implement data loss prevention (DLP) strategies tailored for mobile devices to detect and prevent unauthorized data access or exfiltration. 7. Regularly review and audit app permissions and installed applications to minimize exposure.
