Local app bypass of Gatekeeper checks
Published Sep 14, 2026 · Updated Sep 14, 2026
Security-control bypass in Apple macOS before 27 allows local users to run an app that evades Gatekeeper checks. The disclosed record says improved checks corrected the issue but does not identify the affected Gatekeeper locus or the app property that was insufficiently checked. The documented gate is app execution on a Mac, and the bounded consequence is bypass of Gatekeeper rather than a separately reported compromise.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
