CVE-2025-24255

Sandbox escape via improper file-access validation

Published Mar 31, 2025 · Updated Apr 2, 2026

Improper input validation in Disk Images in Apple macOS allows local users to run an app that breaks out of its sandbox. Apple identifies the locus only as Disk Images and has not published the file-access operation or input that the component validates incorrectly. The local app gate applies to Ventura before 13.7.5, Sonoma before 14.7.5, and Sequoia before 15.4; the bounded impact is loss of the app-sandbox boundary.
