CVE-2026-56161Network attack vector

Authenticated information disclosure

Published Aug 6, 2026 · Updated Aug 25, 2026

Improper access control in Microsoft Azure Logic Apps allows remote authenticated users to read data over the network. Microsoft's advisory and the CNA record do not identify the affected component or request path, disclosing only that authorization is enforced incorrectly in the hosted service. The published record requires low privileges and no user interaction, so exposure is limited to accounts that can reach the service, with disclosed impact bounded to unauthorized data read.
