services / Azure / Azure Key Vault keys

A cryptographic key stored in an Azure Key Vault (software- or HSM-protected). These keys are used for encryption, decryption, signing, key wrapping, and as customer-managed encryption keys (CMK) protecting downstream services and data.

Key Vault keys are among the most sensitive assets in a cloud tenant: they underpin envelope encryption, disk/storage/database encryption, and code/token signing. Private key material is non-exportable via normal reads, so the headline risk varies sharply by operation (read vs. crypto-oracle vs. export).

Microsoft.​KeyVault/​Vaults/​keys/​rotate/​action

Creates a new version of an existing key using the same parameters, letting an attacker force an out-of-cycle rotation to a new key version they can then further manipulate (e.g. import/backup timing), or disrupt applications pinned to a specific key version.

Risks

1. Data manipulation (HIGH)
2. Account persistence (BOOST)

Scope: CRITICAL

This privilege may grant access to sensitive data from a significant fraction of organizational functions, allow interruption of critical organizational services, or its exploit could lead to significant privilege escalation.
