Local privilege escalation via improper path validation
Published Sep 14, 2026 · Updated Sep 14, 2026
Path handling in Apple macOS before 15.8, before 26.7, or before 27 allows local users to gain elevated privileges through a malicious app. Apple identifies only a path-validation failure and has not published the affected component, path operation, or input-flow details. Execution of an attacker-controlled app is required; successful exploitation raises that app's privileges, while the disclosed record does not establish root access.

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.
- Affected versionversion=0 <15.8
- Affected versionversion=0 <26.7
