As a result, if a service has a method with a name that is a prefix of the name of a different method, and they have different access rules, and case-insensitive matching is used, this bug can cause improper authentication.\n\n### Patches\n\nThis vulnerability is fixed in 1.13.1 and 1.14.1.\n\n### Workarounds\nThis problem can be avoided by enabling case-sensitive path matching.","state":0,"publishedAt":"2026-09-28T19:43:51+00:00","modifiedAt":"2026-10-14T05:15:05.7424652+00:00","affected":[{"ecosystem":"npm","name":"@grpc/grpc-js-xds","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.13.1"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"@grpc/grpc-js-xds","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"1.14.0"},{"kind":"fixed","version":"1.14.1"}]}],"versions":["1.14.0"],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/grpc/grpc-node/security/advisories/GHSA-88h9-xgvx-hvf2","https://github.com/grpc/grpc-node/commit/6cf64b596da03f1942a6b168998f0670217a99c4","https://github.com/grpc/grpc-node/commit/a6c5b31180cc8cea94d0a5ea215ce31a49e0409f","https://github.com/grpc/grpc-node/commit/f32f3712e44581d8dfc8359bd8d30096662f4c75","https://github.com/grpc/grpc-node","https://github.com/grpc/grpc-node/releases/tag/@grpc/grpc-js-xds%401.13.1","https://github.com/grpc/grpc-node/releases/tag/@grpc/grpc-js-xds%401.14.1"],"sourceUrl":"https://github.com/advisories/GHSA-88h9-xgvx-hvf2","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-88h9-xgvx-hvf2","identifiers":["GHSA-88h9-xgvx-hvf2","CVE-2026-101914"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
