This could compromise the confidentiality and integrity of data and system operations, as the app may acquire access beyond its intended boundaries. The issue is tied to Access Rights Management weaknesses, corresponding to CWE-284 and CWE-285.", "risk_and_exploitability": "The CVSS score of 4.0 classifies the vulnerability as low severity, and the EPSS score of less than 1% suggests a low probability of exploitation at present. The likely attack vector is a malicious application that gains initial execution rights on the target device, which can then leverage the sandbox escape to gain elevated privileges. Although the risk is currently low, the capability to break out of a sandbox represents a serious escalation path if exploited. The vulnerability is not currently in the CISA KEV catalog."}}}}, "created": "2026-03-25T11:37:07.406901+00:00", "updated": "2026-03-26T12:18:31.466912+00:00", "vendors": ["apple", "apple$PRODUCT$macos"]}
