services / Azure / Storage Blob Service Blobs

Blobs are the individual data objects (files) stored inside containers of an Azure Storage account's blob service. They hold an organization's unstructured production data such as documents, backups, media, and application data.

Data-plane access to blobs directly exposes stored organizational data; ADLS Gen2 (hierarchical namespace) accounts also expose POSIX ownership/ACLs at the blob level.

Microsoft.​Storage/​storageAccounts/​blobServices/​containers/​blobs/​deleteBlobVersion/​action

Deletes a specific historical version of a blob. Blob versioning exists as a recovery control against accidental or malicious overwrite/deletion of the current version; deleting prior versions destroys that recovery path in addition to the version's data.

Risks

1. Data destruction (CRITICAL)

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.
