Unauthenticated notebook spoofing via undisclosed injection
Published May 12, 2026 · Updated May 12, 2026
Injection in Microsoft Azure Machine Learning allows remote attackers to spoof notebook content over a network after user interaction. Microsoft has not disclosed the notebook locus or the untrusted output that reaches a downstream component, so the faulty transformation is not public. Exploitation requires a victim action and can expose notebook data or alter displayed content, without interrupting 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.
