EXECUTIVE SUMMARY:
CVE-2026-32173 with a CVSS score of 8.6 is a high-severity authentication flaw in Microsoft's Azure SRE Agent, exposing sensitive agent data to unauthorized network access. The affected product is the Azure SRE Agent, specifically the Gateway SignalR Hub, which is utilized for real-time communication between agents and the Azure SRE Agent's command stream. The vulnerability stems from a multi-tenant authentication gap in the service, allowing access to data streams without valid credentials. An attacker can exploit this issue by leveraging the predictable and enumerable subdomain of the target agent, requiring only 15 lines of Python code, and gaining access to user prompts, agent responses, internal reasoning traces, every command executed with full arguments, and command output. By exploiting this vulnerability, an attacker gains the capability to silently eavesdrop on enterprise cloud operations, including the ability to view deployment credentials for live web applications. The business impact and consequences of exploitation include the unauthorized disclosure of sensitive information, such as user prompts, internal reasoning, and credentials, with potentially devastating effects on an organization's security posture.[/subscribe_to_unlock_form]
