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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-187","CWE-863"],"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"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-101914","score":0.00251,"percentile":0.1635,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-88h9-xgvx-hvf2","url":"https://osv.dev/vulnerability/GHSA-88h9-xgvx-hvf2","summary":"@grpc/grpc-js: The exact path match matcher incorrectly only applies a prefix match for case-insensitive matches","modified":"2026-10-14T05:15:05.742465218Z","packages":[{"ecosystem":"npm","name":"@grpc/grpc-js-xds","purl":"pkg:npm/%40grpc/grpc-js-xds","ranges":["<1.13.1"],"fixed":["1.13.1"]},{"ecosystem":"npm","name":"@grpc/grpc-js-xds","purl":"pkg:npm/%40grpc/grpc-js-xds","ranges":[">=1.14.0 <1.14.1"],"fixed":["1.14.1"]}]}],"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).
