Exploitability requires an app that can invoke the flawed path parsing logic, which means the threat is primarily local to the device and depends on the installation of malicious or compromised software. If exploited, the primary impact is a confidentiality breach whereby sensitive files become accessible to the attacker. No remote exploitation vector is documented, so the overall risk is significant but the likelihood remains modest."}}}}, "created": "2026-03-25T11:36:39.306553+00:00", "title": "Directory Path Parsing Vulnerability Allowing Unintended Sensitive Data Access", "updated": "2026-03-27T09:53:46.624370+00:00", "vendors": ["apple", "apple$PRODUCT$ios_and_ipados", "apple$PRODUCT$macos", "apple$PRODUCT$visionos"]}
