Nonetheless, because the flaw enables arbitrary elevation to root, the potential impact is critical. It is inferred that the attacker must supply a malicious directory path through an application that processes such paths; the exploit would be executed within the context of that application, possibly through a bundled or downloaded component. Because the vulnerability involves local path parsing, the likely attack vector involves a user\u2011installed application or script executing with elevated privileges on a device."}}}}, "created": "2026-04-28T19:15:25.438362+00:00", "title": "Directory Path Parsing Flaw Allowing Root Privilege Escalation on Apple Devices", "updated": "2026-04-28T19:15:25.438380+00:00", "vendors": []}
