# CVE-2026-44902

## Summary

- **CVE ID:** CVE-2026-44902
- **Severity:** HIGH
- **CVSS Score:** 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
- **CWE:** CWE-755
- **Published:** May 27, 2026
- **Last Modified:** May 28, 2026

## Description

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.

## Affected Products

- open-telemetry — opentelemetry-js (< 0.217.0)
- @opentelemetry — exporter-prometheus (< 0.217.0)
- @opentelemetry — sdk-node (< 0.217.0)
- @opentelemetry — auto-instrumentations-node (< 0.75.0)
