CVE-2024-47217Network attack vector

Authenticated service halt via unbounded JSON depth

Published Apr 3, 2025 · Updated Apr 7, 2025

Denial of service in Snowplow Iglu Server 0.13.0 and earlier allows remote authenticated users to halt schema service requests. The /api/auth/keygen endpoint parses arbitrarily deep nested JSON without enforcing a maximum depth, exhausting processing resources and leaving the server unresponsive. Successful exploitation requires a valid API key; sustained unavailability eventually halts event processing in the Snowplow pipeline.
