{"id":"CVE-2026-101914","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-101914","generatedAt":"2026-10-28T04:17:10.686Z","title":"@grpc/grpc-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon.","description":"@grpc/grpc-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. 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.","published":"2026-09-28T20:17:09.000Z","lastModified":"2026-09-30T19:57:08.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:N"},"cwe":["CWE-187","CWE-863"],"affected":[],"epss":{"score":0.00251,"percentile":0.16425,"date":"2026-10-27","history":[{"date":"2026-09-29","score":0.00251,"percentile":0.14826}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.25%).
