Prior to 1.13.1 and 1.14.1, the exact path (method name) matcher used by RBAC performs a prefix comparison instead of an equality comparison when case-insensitive matching is enabled. If one service method name prefixes another and the methods have different access rules, a request for the longer method can match the shorter method's rule and cause incorrect authorization. This issue is fixed in versions 1.13.1 and 1.14.1.","state":0,"publishedAt":"2026-09-28T20:17:09.453+00:00","modifiedAt":"2026-09-30T19:57:08.043+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:N","score":6.5,"severity":"MEDIUM"}],"references":["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/releases/tag/@grpc/grpc-js-xds%401.13.1","https://github.com/grpc/grpc-node/releases/tag/@grpc/grpc-js-xds%401.14.1","https://github.com/grpc/grpc-node/security/advisories/GHSA-88h9-xgvx-hvf2"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-101914","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-187","CWE-863"],"productCriteria":[],"sourceDates":{"published":"2026-09-28T20:17:09.453","lastModified":"2026-09-30T19:57:08.043"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
