CVE-2026-73553

NVD: Envoy is an open source edge and service proxy designed for cloud-native applications. NVD: Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, When ignore_path_parameters_in_path_matching is enabled, Envoy's router strips the semicolon suffix before matching but the RBAC url_path matcher evaluates the raw path. NVD: A downstream request such as /admin;x can therefore miss a DENY rule for /admin while the router still selects the protected /admin backend.
