CVE-2023-23382Network attack vector

Credential disclosure via plaintext workbook storage

Published Feb 14, 2023 · Updated Aug 19, 2026

Cleartext credential storage in Azure Machine Learning Compute Instance allows remote authenticated users to read stored credentials. The service writes credentials used by workbooks to plaintext workspace resources, including Azure file shares and storage blobs, instead of protecting them from workspace users. A user with workspace access can recover those credentials for further access; the flaw does not alter data or interrupt service.
