CVE-2025-46283 is a logic-based vulnerability identified in Apple macOS operating systems, specifically addressed in versions Sonoma 14.8.4 and Tahoe 26.2. The root cause is an insufficient validation mechanism within the OS that allows an application to bypass intended access controls and retrieve sensitive user data. This vulnerability falls under CWE-200, indicating exposure of sensitive information to unauthorized actors. The attack vector requires local access (AV:L) and user interaction (UI:R), but no privileges (PR:N) or authentication are necessary, making it feasible for a malicious app to exploit once installed and executed by the user. The vulnerability does not impact data integrity or system availability but poses a significant confidentiality risk as sensitive user information can be accessed without proper authorization. The CVSS v3.1 base score is 5.5, reflecting medium severity due to the combination of local attack vector and the need for user interaction. No public exploits have been reported to date, but the presence of this flaw underscores the importance of applying the patches provided by Apple. The vulnerability affects all macOS versions prior to the patched releases, potentially impacting a wide range of users and organizations relying on Apple’s desktop OS.

The primary impact of CVE-2025-46283 is unauthorized disclosure of sensitive user data, which can lead to privacy violations, identity theft, or leakage of confidential corporate information. For organizations, this could result in data breaches, regulatory compliance issues, and reputational damage. Since the vulnerability requires local access and user interaction, the risk is higher in environments where users frequently install third-party or untrusted applications. Attackers could leverage this flaw to escalate information gathering capabilities within a compromised system, facilitating further attacks or espionage. Although the vulnerability does not affect system integrity or availability, the confidentiality breach alone can have severe consequences, especially for sectors handling sensitive personal or business data. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits over time. Organizations with macOS endpoints should consider this vulnerability a significant concern, particularly in industries such as finance, healthcare, and government where data sensitivity is paramount.

To mitigate CVE-2025-46283, organizations should immediately deploy the security updates macOS Sonoma 14.8.4 and macOS Tahoe 26.2 or later, which contain the fix for this logic validation issue. Beyond patching, implement strict application control policies to restrict installation of untrusted or unsigned applications, reducing the likelihood of malicious apps exploiting this vulnerability. Employ endpoint protection solutions capable of detecting suspicious local app behaviors and monitor for unusual access to sensitive data. Educate users about the risks of installing unknown software and the importance of cautious interaction with applications. Use macOS’s built-in privacy controls to limit app permissions to sensitive data where feasible. Regularly audit installed applications and system logs for signs of exploitation attempts. In high-security environments, consider deploying additional sandboxing or containerization techniques to isolate applications and minimize data exposure. Finally, maintain a robust incident response plan to quickly address any suspected compromise involving sensitive data leakage.
