Technical details
The vulnerability is an authorization bypass in Azure Cosmos DB that stems from improper validation of user-controlled keys used in authentication or access control. An attacker with valid credentials can craft or modify these keys to circumvent authorization checks and perform spoofing attacks over the network. The flaw allows an authenticated user to escalate privileges or access data belonging to other users. The attack requires the attacker to already have some form of network access and valid credentials to the service, limiting the attack surface to authorized or previously compromised accounts.
