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.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 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,"severity":null}],"references":["https://github.com/grpc/grpc-node/security/advisories/GHSA-m9gg-hp2v-232j","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"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-88476","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 28, 2026, 8:01:53 PM","dateUpdated":"Oct 1, 2026, 2:54:55 PM"},"relatedAdvisories":[{"id":"RHSA-2026:80603","title":"Red Hat Security Advisory: Ansible plug-ins for Red Hat Developer Hub Product Release Update","vulnerabilityIds":["CVE-2026-47686","CVE-2026-47698","CVE-2026-84961","CVE-2026-85152","CVE-2026-92934","CVE-2026-92935","CVE-2026-92937","CVE-2026-92938","CVE-2026-92939","CVE-2026-92940","CVE-2026-92941","CVE-2026-92944","CVE-2026-92946","CVE-2026-92947","CVE-2026-92948","CVE-2026-92950","CVE-2026-92951","CVE-2026-92953","CVE-2026-92954","CVE-2026-92956","CVE-2026-92957","CVE-2026-92960","CVE-2026-93603","CVE-2026-93604","CVE-2026-93605","CVE-2026-93606","CVE-2026-101916"]},{"id":"RHSA-2026:80644","title":"Red Hat Security Advisory: Ansible plug-ins for Red Hat Developer Hub Product Release Update","vulnerabilityIds":["CVE-2026-47686","CVE-2026-47698","CVE-2026-84961","CVE-2026-85152","CVE-2026-92934","CVE-2026-92935","CVE-2026-92937","CVE-2026-92938","CVE-2026-92939","CVE-2026-92940","CVE-2026-92941","CVE-2026-92944","CVE-2026-92946","CVE-2026-92947","CVE-2026-92948","CVE-2026-92950","CVE-2026-92951","CVE-2026-92953","CVE-2026-92954","CVE-2026-92956","CVE-2026-92957","CVE-2026-92960","CVE-2026-93603","CVE-2026-93604","CVE-2026-93605","CVE-2026-93606","CVE-2026-101916"]},{"id":"RHSA-2026:90321","title":"Red Hat Security Advisory: Red Hat OpenShift Dev Spaces 3.31.0 Release.","vulnerabilityIds":["CVE-2023-54404","CVE-2025-62718","CVE-2026-8643","CVE-2026-9496","CVE-2026-12185","CVE-2026-13697","CVE-2026-14682","CVE-2026-15076","CVE-2026-16308","CVE-2026-17106","CVE-2026-18427","CVE-2026-19203","CVE-2026-19534","CVE-2026-39820","CVE-2026-41178","CVE-2026-41707","CVE-2026-42499","CVE-2026-42502","CVE-2026-45416","CVE-2026-47884","CVE-2026-47886","CVE-2026-47888","CVE-2026-47890","CVE-2026-47892","CVE-2026-50010","CVE-2026-55831","CVE-2026-55833","CVE-2026-55851","CVE-2026-56745","CVE-2026-56746","CVE-2026-56819","CVE-2026-56852","CVE-2026-56854","CVE-2026-58062","CVE-2026-59280","CVE-2026-59282","CVE-2026-59283","CVE-2026-59296","CVE-2026-59313","CVE-2026-59323","CVE-2026-59651","CVE-2026-59887","CVE-2026-59899","CVE-2026-59901","CVE-2026-62243","CVE-2026-64607","CVE-2026-67213","CVE-2026-67312","CVE-2026-67313","CVE-2026-67314","CVE-2026-67320","CVE-2026-67321","CVE-2026-68494","CVE-2026-68497","CVE-2026-69152","CVE-2026-69192","CVE-2026-71290","CVE-2026-71324","CVE-2026-71325","CVE-2026-71327","CVE-2026-73500","CVE-2026-73508","CVE-2026-74835","CVE-2026-75838","CVE-2026-75899","CVE-2026-75931","CVE-2026-76169","CVE-2026-81521","CVE-2026-82417","CVE-2026-82562","CVE-2026-84292","CVE-2026-84375","CVE-2026-84394","CVE-2026-84428","CVE-2026-84445","CVE-2026-84469","CVE-2026-84504","CVE-2026-84961","CVE-2026-85062","CVE-2026-85124","CVE-2026-85152","CVE-2026-85595","CVE-2026-85597","CVE-2026-86063","CVE-2026-87743","CVE-2026-88004","CVE-2026-88007","CVE-2026-88008","CVE-2026-88009","CVE-2026-88011","CVE-2026-88012","CVE-2026-88031","CVE-2026-88878","CVE-2026-88879","CVE-2026-90711","CVE-2026-93749","CVE-2026-100655","CVE-2026-100656","CVE-2026-100666","CVE-2026-101916","CVE-2026-102925","CVE-2026-102930","CVE-2026-103435","CVE-2026-109618","CVE-2026-109619"]},{"id":"RHSA-2026:88198","title":"Red Hat Security Advisory: Red Hat Developer Hub 1.10.6 release.","vulnerabilityIds":["CVE-2026-84782","CVE-2026-90711","CVE-2026-93748","CVE-2026-93749","CVE-2026-101916"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
