Apache APISIX 2.14.13.18.0 Non-Canonical URL Path Auth Bypass
CVE-2026-94269 Published on October 1, 2026
Apache APISIX: Servlet-style normalization creates a route/upstream authorization mismatch
Use of Non-Canonical URL paths for authorization decisions vulnerability in Apache APISIX.
In some configurations where a permissive route overlaps a protected one, a crafted encoded path can reach an upstream endpoint that the matched route's policies were never meant to cover. A request that should have been rejected is served instead, giving unauthenticated access to a protected upstream endpoint. This issue affects Apache APISIX: from 2.14.1 through 3.18.0.
Users are recommended to upgrade to version 3.19.0, which fixes the issue.
