CVE-2022-23254Network attack vector

Access-token disclosure via exception objects

Published Feb 9, 2022 · Updated Jan 2, 2025

Information disclosure in Microsoft powerbi-client 2.0.0 through 2.19.0 allows remote authenticated users to obtain a Power BI access token. The SDK leaves configured access tokens in exception objects rather than removing the credential before exposing error details. Exploitation requires network access and high privileges, and the resulting disclosure is limited to confidentiality of the exposed token.
