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."}], "lastModified": "2026-09-30T19:57:08.043", "sourceIdentifier": "security-advisories@github.com"}
