Protection mechanism failure in Apple's macOS before 15.4 allows local users to escape an app sandbox through the quarantine component. The quarantine component performs insufficient checks to prevent unauthorized actions, but Apple has not disclosed the affected operation or input. Exploitation requires code execution inside an app sandbox and removes that confinement; no further privilege or data impact is publicly reported.
