Microsoft Azure Resource Manager. No specific version information is provided by the citation; administrators should verify that their ARM instance is up to date.

The CVSS score of 10 underscores the high severity of this exploitation. The EPSS score of 0.00065 (<1%) indicates a very low current exploit probability, but the vulnerability remains listed outside the CISA KEV catalog. The nature of the flaw allows a remote attacker with network access to ARM APIs to potentially elevate privileges without credential validation. The impact scope can reach organization-wide resources if the attacker accesses high-privilege accounts. Immediate action is recommended to mitigate the risk.
