Apple WebKit Sandbox Bypass Vulnerability

A race condition vulnerability has been identified in the WebKit component of Apple macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, and macOS Tahoe 26.4. This vulnerability allows a sandboxed process to potentially circumvent sandbox restrictions, which could lead to unauthorized access or actions within the user's environment.

Impact

Exploitation of this vulnerability could allow a sandboxed process to break out of its sandbox, bypassing restrictions meant to isolate applications and protect system resources.

Reproduction

The vulnerability can be reproduced by creating a sandboxed process that interacts with the printing system. The race condition can be exploited by timing the interaction in such a way that the process circumvents the intended sandbox restrictions.

Remediation

Users can update to macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, or macOS Tahoe 26.4 to address this vulnerability.
