Location disclosure via unredacted CFNetwork diagnostic logs
Published Sep 6, 2023 · Updated Feb 13, 2025
Information disclosure in CFNetwork in Apple macOS before 13.5 allows context-dependent attackers to read location data through an app. CFNetwork diagnostic logging records request URLs containing precise location coordinates without adequately redacting those private values. Exploitation requires execution of an attacker-controlled app and user interaction; the demonstrated consequence is disclosure of sensitive location data from local logs.

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.
