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":"2026-09-28T19:36:55.746+00:00","modifiedAt":"2026-09-29T19:21:17.564+00:00","affected":[{"ecosystem":"Vendor product","name":"grpc-node","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"grpc\",\n                    \"product\": \"grpc-node\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.13.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 1.14.0, < 1.14.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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/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/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://www.cve.org/CVERecord?id=CVE-2026-101914","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-101914","identifiers":["CVE-2026-101914"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
