CosmosEscape: Taking Over Every Database in Azure Cosmos DB

Yuval Avrahami and Lior Maman · Wiz Research · 30 July 2026

AI-collected research leads through 6 October 2026, including bounded month-by-month reviews of selected social and community sources from January through September. Unranked, incomplete, not community-vetted, and subject to change.

Traces a Gremlin query escape into a shared Cosmos DB gateway, then follows gateway credentials through a signing key to account primary keys. A regional configuration lookup locates target tenants, linking query execution, credential scope and gateway-enforced network isolation in the described cross-account access chain.
