CVE-2025-43524: An app may be able to break out of its sandbox in Apple macOS Sequoia
CVE-2025-43524 is a high-severity vulnerability in Apple macOS Sequoia and related versions where an app may be able to break out of its sandbox due to an access issue. Apple addressed this issue by adding additional sandbox restrictions and fixed it in macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, and macOS Tahoe 26.2. The vulnerability allows an app with limited privileges to potentially escalate its privileges and compromise confidentiality, integrity, and availability of the system. No known exploits are reported in the wild at this time.
AI Analysis
Technical Summary
This vulnerability involves an access control weakness in the sandbox implementation of Apple macOS Sequoia and related versions. The sandbox is designed to isolate apps and restrict their capabilities, but due to insufficient restrictions, an app may escape this sandbox. Apple has fixed the issue by enhancing sandbox restrictions in specific macOS versions: Sequoia 15.7.7, Sonoma 14.8.7, and Tahoe 26.2. The CVSS v3.1 base score is 8.8, indicating a high impact with local attack vector, low attack complexity, requiring low privileges but no user interaction, and resulting in complete confidentiality, integrity, and availability compromise.
Potential Impact
Successful exploitation allows an app to break out of its sandbox, potentially leading to full system compromise including unauthorized access to sensitive data, modification of system components, and disruption of system availability. The vulnerability affects confidentiality, integrity, and availability at a high level.
Mitigation Recommendations
A fix is available and has been released by Apple in macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, and macOS Tahoe 26.2. Users and administrators should apply these updates to remediate the vulnerability. No additional mitigation guidance is provided or required beyond applying the official patches.
