Prior to 1.13.6 and 1.14.5, getAuthContext does not distinguish authorized from unauthorized peer certificates when server credentials set requireClientCertificate to false. When applications use the returned authentication context, they can treat an unauthorized certificate as authorized, causing improper authentication. @grpc/grpc-js-xds can reach this condition when RBAC authentication is enabled in affected configurations. This issue is fixed in version 1.14.5 and 1.13.6.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4},"cwes":["CWE-295"],"references":["https://github.com/grpc/grpc-node/commit/2a84ec8b01b9db68ed9d2b117a53a81449edb8ee","https://github.com/grpc/grpc-node/commit/b4e0079c6d22a2adedfcac748e0bc083f783bc7c","https://github.com/grpc/grpc-node/releases/tag/@grpc/grpc-js%401.14.5","https://github.com/grpc/grpc-node/security/advisories/GHSA-m9gg-hp2v-232j"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-101916","score":0.00215,"percentile":0.11833,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-m9gg-hp2v-232j","url":"https://osv.dev/vulnerability/GHSA-m9gg-hp2v-232j","summary":"@grpc/grpc-js: In certain configurations, getAuthContext can return unauthorized certificates as though they were authorized","modified":"2026-09-30T15:45:30.357039902Z","packages":[{"ecosystem":"npm","name":"@grpc/grpc-js","purl":"pkg:npm/%40grpc/grpc-js","ranges":["<1.13.6"],"fixed":["1.13.6"]},{"ecosystem":"npm","name":"@grpc/grpc-js","purl":"pkg:npm/%40grpc/grpc-js","ranges":[">=1.14.0 <1.14.5"],"fixed":["1.14.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
