CVE-2025-30453 is a vulnerability in Apple macOS that allows a malicious application to gain root privileges by exploiting insufficient permission checks. The vulnerability is classified under CWE-280, which relates to improper access control or permission issues. It affects multiple versions of macOS prior to the patched releases: Sequoia 15.4, Ventura 13.7.6, and Sonoma 14.7.6. The vulnerability requires the attacker to have local access with low privileges (AV:L - local attack vector, PR:L - low privileges) but does not require user interaction (UI:N). The CVSS v3.1 base score is 7.8, indicating a high severity level, with impacts rated high on confidentiality, integrity, and availability. The vulnerability allows an attacker to escalate privileges to root, potentially enabling full control over the affected system. Apple addressed the issue by implementing additional permission checks to prevent unauthorized privilege escalation. No known exploits are currently reported in the wild, but the vulnerability poses a significant risk if exploited. The vulnerability’s exploitation scope is limited to local attackers but can be leveraged in targeted attacks or combined with other vulnerabilities for broader compromise.

The impact of CVE-2025-30453 is significant for organizations relying on macOS devices. Successful exploitation grants an attacker root privileges, enabling full system control, including access to sensitive data, installation of persistent malware, disabling security controls, and disruption of system availability. This can lead to data breaches, intellectual property theft, and operational disruptions. Since the vulnerability requires only local access with low privileges and no user interaction, it can be exploited by malicious insiders, compromised user accounts, or through other local attack vectors such as malicious scripts or apps. Organizations with macOS endpoints in sensitive environments—such as government, finance, healthcare, and technology sectors—face elevated risks. The vulnerability also increases the attack surface for advanced persistent threat (APT) actors targeting Apple ecosystems. Without timely patching, the risk of privilege escalation attacks and subsequent lateral movement within networks is heightened.

To mitigate CVE-2025-30453, organizations should immediately deploy the security updates provided by Apple in macOS Sequoia 15.4, Ventura 13.7.6, and Sonoma 14.7.6. Beyond patching, organizations should implement strict application whitelisting and endpoint protection to prevent execution of unauthorized or suspicious applications. Employing least privilege principles for user accounts reduces the risk of local privilege escalation. Monitoring and logging of local privilege escalation attempts and unusual system behavior can help detect exploitation attempts early. Restrict local access to macOS systems, especially in shared or public environments, and enforce strong authentication mechanisms to limit attacker footholds. Regularly audit installed applications and remove unnecessary software to reduce attack vectors. For environments with high security requirements, consider using macOS security features such as System Integrity Protection (SIP) and Endpoint Security Framework to enhance protection against privilege escalation.
