Unauthenticated network information disclosure
Published Mar 10, 2026 · Updated Mar 10, 2026
Information disclosure in Microsoft Azure IoT Explorer before 0.15.13 allows remote attackers to read data through network requests. Microsoft identifies a failure to restrict a communication channel to its intended endpoints but does not disclose the affected code path or endpoint-selection error. Exploitation requires network reachability to the application's communications and grants access to information only, with no reported ability to modify data or interrupt service.

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.
