CVE-2025-24204 is a critical security vulnerability identified in Apple macOS, specifically affecting versions before macOS Sequoia 15.4. The vulnerability arises from insufficient access control checks within the operating system, allowing an unprivileged application to bypass protections and access sensitive user data that should otherwise be restricted. This is categorized under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The vulnerability does not require any privileges or user interaction to exploit, making it remotely exploitable with network access. The CVSS v3.1 base score of 9.8 reflects the high severity, with attack vector being network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impacts on confidentiality, integrity, and availability all rated high (C:H/I:H/A:H). Apple addressed this issue by implementing improved access control checks in macOS Sequoia 15.4, which prevents unauthorized apps from accessing protected user data. While no known exploits have been reported in the wild as of the publication date, the vulnerability's characteristics suggest that exploitation could lead to significant data breaches and system compromise. The flaw could be leveraged by attackers to steal sensitive information, manipulate data integrity, or disrupt system availability, potentially facilitating further attacks or espionage.

The impact of CVE-2025-24204 on organizations worldwide is substantial due to the critical nature of the vulnerability. Successful exploitation allows attackers to access protected user data without any authentication, leading to severe confidentiality breaches. This can result in exposure of personally identifiable information (PII), intellectual property, credentials, or other sensitive data. The integrity and availability impacts imply that attackers could also modify or disrupt data and system operations, potentially causing operational downtime or data corruption. For enterprises relying on macOS devices for business-critical functions, this vulnerability could facilitate lateral movement within networks, espionage, or ransomware deployment. The lack of required privileges or user interaction lowers the barrier for attackers, increasing the likelihood of exploitation. Although no active exploits are currently known, the vulnerability presents a high risk, especially for sectors handling sensitive data such as finance, healthcare, government, and technology. Organizations failing to patch promptly may face regulatory penalties, reputational damage, and financial losses due to data breaches or operational disruptions.

To mitigate CVE-2025-24204, organizations must prioritize updating all macOS systems to version Sequoia 15.4 or later, where the vulnerability is fixed by enhanced access control checks. Beyond patching, organizations should implement strict application whitelisting and restrict installation of untrusted or unnecessary applications to reduce exposure. Employ endpoint detection and response (EDR) solutions capable of monitoring unusual access patterns to protected data. Network segmentation can limit the ability of compromised devices to access sensitive resources. Regularly audit and enforce least privilege principles for user accounts and applications. Additionally, enable macOS security features such as System Integrity Protection (SIP) and Transparency, Consent, and Control (TCC) to strengthen data access controls. Conduct user awareness training to recognize suspicious application behavior, even though user interaction is not required for this exploit. Finally, maintain comprehensive backups and incident response plans to quickly recover from potential data integrity or availability impacts.
