  • 16-Year-Old Researcher Finds Microsoft Titan Auth Flaw Exposing 17.3 Trillion Records
    A 16-year-old researcher found a JWT authentication flaw in Microsoft's internal Titan analytics service that allowed forged admin access to an estimated 17.3 trillion database rows.
    • Applies to Microsoft's internal Titan analytics service, hosted via Azure Cloud Services, with a public API exposing a /v2/Query route that accepted raw SQL.
    • Titan validated JWT claims (tenant ID, audience, app ID, user identity) but never cryptographically verified the token signature, accepting an 'alg: none' token with an empty signature.
    • Setting the token's upn claim to 'admin' mapped to local user ID 1 with the Admin role, enabling unauthorized SQL queries; metadata exposed included ~25,000 account records, 17,990 employee emails, 355 database configs, and 24,569 dashboards.
    • Testing 56 archived routing values found 30 active routes resolving to 17 ClickHouse databases with 9,863 tables, yielding an estimated 17,333,335,124,315 rows โ€” likely including historical and duplicated records, not unique individuals.
    • Reported to MSRC on September 5, 2026 (case 144051); Microsoft locked down the endpoint on September 9 and paid a $5,000 bounty; no evidence of malicious exploitation or customer PII access.
