CVE-2026-94269Network attack vectorHinoki check available

Unauthenticated upstream access via encoded-path route mismatch

Published Oct 1, 2026 · Updated Oct 1, 2026

Authorization bypass in Apache APISIX 2.14.1 through 3.18.0 allows remote attackers to access protected upstream endpoints via encoded paths. HTTP route matching uses a processed request path, while upstream forwarding can preserve a different path representation, causing a permissive route's policies to govern a protected endpoint. Exploitation requires overlapping permissive and protected routes; the established consequence is access to the upstream endpoint without its intended route authorization.
