Information disclosure via unfiltered data-plane requests
Published Mar 10, 2026 · Updated Mar 10, 2026
SSRF in Microsoft Azure IoT Explorer before 0.15.14 allows remote attackers to read data from network-reachable services. The port 8081 data-plane handler forwards attacker-controlled destinations without filtering private or reserved network targets. Exploitation requires network access to the running application's HTTP service; the published impact is limited to confidentiality.

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=1.0.0 <0.15.14
