CVE-2024-47213
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered affecting Enrich 5.1.0 and below. It involves sending a maliciously crafted Snowplow event to the pipeline. Upon receiving this event and trying to validate it, Enrich crashes and attempts to restart indefinitely. As a result, event processing would be halted.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA denial of service vulnerability in Enrich versions 5.1.0 and below allows attackers to send maliciously crafted Snowplow events that trigger a crash during event validation, causing the service to enter an infinite restart loop and halt all event processing.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Enrich versionQuery the Enrich service version endpoint or inspect the running container/service metadata. If running via Docker, run 'docker ps' and inspect the image tag, or check the enrichment version file if exposed. For Kubernetes, check the image version in the deployment YAML or via 'kubectl get deployment'.Affected if The installed version is 5.1.0 or below, meaning it is less than 5.1.1
-
Verify Enrich service stabilityCheck the Enrich service process or container status. Review logs for repeated crash patterns and restart cycles. Run 'docker ps' or 'kubectl get pods' to observe restart counts. Inspect logs for recurring validation errors followed by process termination.Affected if The Enrich service is experiencing frequent restarts with high restart counts in a short period, indicating an infinite restart loop
-
Confirm event processing haltReview Enrich metrics or logs to verify that no events are being processed. Check for gaps in event throughput dashboards or examine the last successful event processing timestamp. Look for log entries showing the service is down or unable to process incoming events.Affected if Event processing has stopped completely and the service is unable to accept or validate new Snowplow events
A user is affected if running Snowplow Enrich version 5.1.0 or below and experiencing a crash loop that halts all event processing when malformed events are received.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped5.1.1
Update Enrich to a version above 5.1.0 to patch the vulnerability, or implement upstream event filtering to reject malformed events before they reach the Enrich pipeline.
Enrich 5.1.1
- Identify the current version of Enrich in your Snowplow pipeline
- Upgrade Enrich to version 5.1.1 or later
- Restart the Enrich service to apply the update
- Verify that Enrich is running and processing events without crashing
