CVE-2026-94269
MEDIUMDescription
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.
