{"id":"CVE-2026-44902","aliases":["GHSA-q7rr-3cgh-j5r3"],"url":"https://o3.security/vulnerability/CVE-2026-44902","summary":"opentelemetry-js: Prometheus exporter process crash via malformed HTTP request","details":"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.","published":"2026-05-27T14:49:04.940Z","modified":"2026-08-07T11:31:17.977850248Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@opentelemetry/exporter-prometheus","fixedVersion":"0.217.0"},{"ecosystem":"npm","name":"@opentelemetry/sdk-node","fixedVersion":"0.217.0"},{"ecosystem":"npm","name":"@opentelemetry/auto-instrumentations-node","fixedVersion":"0.75.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44902.json"},{"type":"ADVISORY","url":"https://github.com/open-telemetry/opentelemetry-js/security/advisories/GHSA-q7rr-3cgh-j5r3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44902"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:17.977850248Z"}}
