The vulnerability is a classic example of improper access control and falls under the CWE-284 category. Once an application can write to these protected locations, it can alter system files or configuration, undermining confidentiality and availability of the operating system. The impact is limited to the local user context that runs the application, but if the application is privileged, the consequences expand to the entire system.", "risk_and_exploitability": "The CVSS base score of 5.5 indicates moderate severity, and the EPSS score of less than 1% suggests low likelihood of exploitation in the wild. The vulnerability was mitigated by removing the vulnerable code, and it is not listed in CISA's KEV catalog. Exploitation would require the attacker to run or trick a user into running a malicious application with the appropriate file system access; therefore, local environmental conditions and user behavior influence the risk. No publicly available remote exploitation path was documented, implying that the attack surface is primarily local."}}}}, "created": "2026-03-25T11:37:03.511655+00:00", "title": "Permissions Issue Allowing Modification of Protected File System Parts in macOS", "updated": "2026-03-29T20:28:38.961235+00:00", "vendors": ["apple", "apple$PRODUCT$macos"], "weaknesses": ["CWE-284"]}
