opentelemetry-js is the OpenTelemetry JavaScript Client. Prior to 0.217.0, 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. This vulnerability is fixed in 0.217.0.

GHSA-q7rr-3cgh-j5r3 — Prometheus exporter process crash via malformed HTTP request

Affected: npm: @opentelemetry/exporter-prometheus, npm: @opentelemetry/sdk-node, npm: @opentelemetry/auto-instrumentations-node

## 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 proces…
