### Prometheus exporter process crash via malformed HTTP request
[CVE-2026-44902](https://nvd.nist.gov/vuln/detail/CVE-2026-44902) /
[GHSA-q7rr-3cgh-j5r3](https://redirect.github.com/advisories/GHSA-q7rr-3cgh-j5r3)

<details>
<summary>More information</summary>

#### Details
##### 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
@&#8203;opentelemetry/auto-instrumentations-node/register`/`--import
@&#8203;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 install @&#8203;opentelemetry/exporter-prometheus@latest
```

##### Do Not Expose the Endpoint to Untrusted Users

> [!IMPORTANT] 
> The following mitigations reduce exposure but do not fully remediate
the vulnerability. Any client that *can* reach the metrics endpoint -
including your own Prometheus scraper host if compromised - could still
trigger the crash. Updating to **0.217.0** is the recommended
resolution.

If updating is not immediately feasible, restrict access to the metrics
endpoint so that it is not reachable by untrusted or unauthenticated
network clients. For example:

* **Bind to localhost only** by setting the `host` option to `127.0.0.1`
when configuring the `PrometheusExporter`, so the port is not exposed on
public or shared network interfaces

* **Use a firewall or network policy** to restrict access to port `9464`
(or whichever port you have configured) to only trusted Prometheus
scrape hosts

* **Place the endpoint behind a reverse proxy** that filters or
validates incoming requests before they reach the exporter

##### Details

In `PrometheusExporter.ts`, the `_requestHandler` calls `new
URL(request.url, this._baseUrl)` without any error handling. Node's HTTP
parser accepts absolute-form URIs (e.g. `http://`) for proxy
compatibility, including malformed ones. When `request.url` is
`"http://"`, the `URL` constructor throws `TypeError: Invalid URL`.
Since there is no try-catch in the handler, the exception propagates as
an uncaught exception and crashes the process.

The Prometheus metrics endpoint is unauthenticated by design (Prometheus
scrapes it) and binds to `0.0.0.0` by default, meaning it is reachable
by any network client that can connect to the metrics port.

##### Proof of Concept

Start any Node.js application with the Prometheus exporter running on
the default port `9464`, then send a single raw TCP packet:

```
echo -ne 'GET http:// HTTP/1.1\r\nHost: localhost\r\n\r\n' | nc localhost 9464
```

The process crashes immediately with:

```
TypeError: Invalid URL
    at new URL (...)
    at PrometheusExporter._requestHandler (...)
```
