Based on the description, it is inferred that an attacker could exploit this issue by delivering or running a malicious application in a context that the system trusts; the application could then traverse directories and read files that should be out of reach. Because the flaw does not provide remote code execution or privilege escalation, the risk is confined to applications already permitted to run on the device."}}}}, "created": "2026-02-12T09:02:19.084946+00:00", "title": "Apple OS Directory Path Parsing Flaw Enabling Unauthorized Data Access", "updated": "2026-04-16T01:00:19.954866+00:00", "vendors": ["apple", "apple$PRODUCT$ios_and_ipados", "apple$PRODUCT$macos", "apple$PRODUCT$visionos"]}
