CVE-2024-47213Network attack vector

Event-processing halt via unchecked JSON nesting

Published Apr 3, 2025 · Updated Apr 4, 2025

Denial of service in Snowplow Enrich 5.1.0 and earlier allows remote attackers to halt event processing via a crafted event. Deeply nested JSON entities reach String-to-Circe conversion before the configured depth limit is enforced, crashing validation and triggering an endless restart loop. The crafted event must enter the pipeline; repeated process restarts halt pipeline event processing without affecting data confidentiality or integrity.
