DescriptionNVD

A race condition was addressed with additional validation. This issue is fixed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4. An app may be able to break out of its sandbox.

AnalysisAI

Sandbox escape vulnerability in macOS (Sequoia 15.7.4 and earlier, Sonoma 14.8.4 and earlier, Tahoe 26.3 and earlier) allows locally-installed applications to break out of their sandbox restrictions through a race condition. An attacker with the ability to run an application on an affected system could exploit this to gain unauthorized access outside the application's intended security boundaries. …

RemediationAI

Within 24 hours: Inventory all macOS systems running Sequoia 15.7.4 or earlier, Sonoma 14.8.4 or earlier, and Tahoe 26.3 or earlier; alert macOS users not to install untrusted applications. Within 7 days: Restrict local application execution policies where feasible and monitor for suspicious sandbox-escape indicators (unusual system call sequences, out-of-process resource access). …
