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":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:L/I:H/A:N","score":6.5,"severity":null}],"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://euvd.enisa.europa.eu/vulnerability/EUVD-2026-88464","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 28, 2026, 7:36:55 PM","dateUpdated":"Sep 29, 2026, 7:21:17 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
