On 26 August 2021 security researchers disclosed a vulnerability in Microsoft’s Azure cloud platform. The following Azure component is affected:
- Cosmos DB
Exploitation of this vulnerability would have exposed credentials that could have allowed an unauthorized actor to view, modify or delete data in Cosmos DB databases.
