CVE-2026-44902
opentelemetry-js: Prometheus exporter process crash via malformed HTTP request
CVSS Score
7.5
EPSS Score
0.0%
EPSS Percentile
4th
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.
