A logic issue was addressed with improved state management. This issue is fixed in macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7. A malicious application may bypass Gatekeeper checks.
AnalysisAI
Gatekeeper protection in Apple macOS can be bypassed by a malicious application, allowing unsigned or unnotarized code to launch on unpatched Macs. The flaw is a state-management logic error in the Gatekeeper check, rated CVSS 5.5 (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N): exploitation is local and requires the victim to download and open an attacker-controlled app, so it depends on user interaction rather than a remote network path, and it yields no confidentiality or availability impact by itself - it must be chained with a malicious payload. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local delivery and execution of a crafted malicious application on the target Mac: the attacker must get the user to download and open the app (UI:R), so success hinges on social engineering rather than any remote network path. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a moderate, not urgent, priority. … 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 | Vendor-released patch: update to macOS Golden Gate 27, macOS Sequoia 15.8, or macOS Tahoe 26.7 as applicable to the installed release line, per Apple advisories https://support.apple.com/en-us/149035, https://support.apple.com/en-us/149042, and https://support.apple.com/en-us/149043. … Detailed patch versions, workarounds, and compensating controls in full report. |
