This issue was addressed with improved checks. This issue is fixed in macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7. An app may be able to gain root privileges.
AnalysisAI
Local privilege escalation in Apple macOS lets an application running with standard user privileges obtain root, giving an attacker full control of the host once code executes on the machine. The flaw is an improper access-control check (CWE-284) that Apple addressed with improved validation logic, fixed in macOS Sequoia 15.8, macOS Tahoe 26.7, and macOS Golden Gate 27. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the ability to execute a program locally on the target Mac under a standard (non-privileged) user account - the CVSS vector PR:L/UI:N confirms low privileges are sufficient and that no additional user interaction beyond launching the application is needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H (7.8) describes a local, low-complexity attack requiring only low privileges and no user interaction beyond launching the application, with total confidentiality, integrity, and availability impact on the host. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released patches: update to macOS Sequoia 15.8, macOS Tahoe 26.7, or macOS Golden Gate 27 depending on the installed release line - Apple's advisories at https://support.apple.com/en-us/149035, https://support.apple.com/en-us/149042, and https://support.apple.com/en-us/149043 document the fixes and should be consulted for the exact build numbers per platform. … Detailed patch versions, workarounds, and compensating controls in full report. |
