{"schema":"threatline.record/2","record":{"id":"CVE-2026-101914","aliases":["GHSA-88h9-xgvx-hvf2"],"summary":"@grpc/grpc-js: The exact path match matcher incorrectly only applies a prefix match for case-insensitive matches","details":"### Impact\nWhen using RBAC to apply authentication rules, the exact path (method name) matcher applies a prefix match instead of an exact match for case-insensitive matches. 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.","categories":["Libraries & packages"],"product":"@grpc/grpc-js-xds","vendor":"grpc","ecosystem":"npm","affected_ranges":[{"source":"GitHub Advisory
