CVE-2026-32207Network attack vector

Unauthenticated notebook spoofing through cross-site scripting

Published May 7, 2026 · Updated May 7, 2026

Cross-site scripting in Microsoft Azure Machine Learning allows remote attackers to spoof notebook content through network requests. Microsoft identifies improper neutralization during web page generation but does not disclose the affected notebook component, input field, or rendering path. Exploitation requires a victim to interact with attacker-controlled content, and the published record limits the stated outcome to spoofing.
