  "method": "structured",
  "payload": {
    "kind": "advisory",
    "title": "Prometheus exporter process crash via malformed HTTP request",
    "summary": "## Summary A single malformed HTTP request crashes any Node.js process running the OpenTelemetry JS Prometheus exporter. The metrics endpoint (default `0.0.0.0:9464`) has no error handling around URL parsing, so a request with an invalid URI causes an uncaught `TypeError` that terminates the process. **You are affected by this vulnerability if either of the following apply to your application:** * you directly use `@opentelemetry/exporter-prometheus` in your code through its built-in server. * your `OTEL_METRICS_EXPORTER` environment variable includes `prometheus` **AND** * you use `@opentelemetry/sdk-node` * you use `@opentelemetry/auto-instrumentations-node` via `--require @opentelemetry/auto-instrumentations-node/register`/`--import @opentelemetry/auto-instrumentations-node/register` ## Impact **Denial of service.** Any application using the OpenTelemetry Prometheus exporter’s built-in server can be crashed by a single unauthenticated network packet sent to the metrics port. No authentication, special privileges, or prior access is required. ## Remediation ### Update to the fixed version Update `@opentelemetry/exporter-prometheus` and `@opentelemetry/sdk-node` to version **0.217.0** or later. Update `@opentelemetry/auto-instrumentations-node` to version **0.75.0** or later. This release adds proper error handling around the URL constructor, returning an HTTP `400` response on parse failure rather than allowing the exception to propagate and crash the process. ``` npm insta",
