Spoofing via undisclosed command injection
Published May 7, 2026 · Updated May 7, 2026
Command injection in Microsoft Azure Cloud Shell allows remote attackers to spoof content through a network request requiring user interaction. Microsoft has not disclosed the affected request handler, command-construction path, or special elements that reach a shell command. Successful exploitation requires user interaction; the public advisory identifies spoofing but does not describe the impersonated content or resulting actions.
