Default Azure Automation Setting Enables Cross-Tenant Identity Takeover
Azure Automation flaw allowed cross-tenant identity takeover and data access.
Microsoft has patched a critical vulnerability in Azure Automation that, when chained with other code flaws, allowed attackers to take over identities in other tenants. This could have led to unauthorized access to sensitive data, credentials, and cloud workloads across different Azure environments.

The lesson from this incident
Full lessonA critical vulnerability in Azure Automation stemmed from an insecure default configuration that, when combined with additional code flaws, allowed attackers to hijack identities across different Azure tenants. Default settings that grant excessive permissions are particularly dangerous in multi-tenant cloud environments because a single misconfiguration can expose not just one organization but many. This incident highlights that cloud services should follow the principle of least privilege by default, not as an optional hardening step. Organizations must never assume that vendor defaults are secure, especially in shared or federated cloud infrastructure where trust boundaries are inherently complex.
What helps against this
How we list vendors
- Privileged access management (PAM)
Admin accounts stop being one stolen password away from control of everything.
- Identity threat detection and response (ITDR)
Attackers who log in with real, stolen credentials get noticed.
- Cloud security posture management (CSPM and CNAPP)
Misconfigured cloud storage and over-permissive roles get caught before they leak.
