The flaw is categorized as a privilege\u2011elevation weakness, potentially enabling an attacker to obtain sensitive information from the affected device. The impact is the unauthorized disclosure of data, which could lead to privacy violations or compromise of user files.", "risk_and_exploitability": "The CVSS score of 7.5 indicates a high severity impact, but the EPSS score of less than 1% suggests that real\u2011world exploitation is currently rare. The flaw does not appear in the CISA KEV catalog, further indicating that widespread exploitation is not yet observed. The likely attack vector is local: a malicious or compromised app executed on the user's machine could read protected data. Administrators should assess whether applications on the system could be tampered with and whether the risk of data exposure outweighs the likelihood of exploitation."}}}}, "created": "2026-03-25T11:36:41.087933+00:00", "title": "macOS App May Access Sensitive User Data Due to Logic Issue", "updated": "2026-03-27T09:19:58.472553+00:00", "vendors": ["apple", "apple$PRODUCT$macos"]}
