CVE-2025-31189

Sandbox escape via file quarantine bypass

Published May 29, 2025 · Updated Apr 2, 2026

File quarantine bypass in Apple macOS allows local users to escape an app sandbox through the Disk Images component. Apple identifies Disk Images as the locus but has not disclosed which quarantine check mishandles untrusted files or how it is bypassed. The attack requires local execution and user interaction; successful exploitation removes the app's sandbox restrictions without affecting system availability.
