Conventional Threats Watchlist

Security researchers at Wiz disclosed a now-patched vulnerability chain in Azure Cosmos DB, dubbed CosmosEscape, that allowed an attacker to escape the Gremlin query sandbox and obtain a platform-wide key granting full read/write access to databases across multiple customer tenants. The flaw originated from a crafted, attacker-controlled Gremlin query that achieved code execution on the underlying host, breaking multi-tenant isolation. Microsoft has remediated the issue; no evidence of in-the-wild exploitation was reported.
