CVE-2026-94269Apache APISIX: Servlet-style normalization creates a route/upstream authorization mismatch
Medium 6.3
In plain English
A medium-severity security flaw in Apache APISIX from Apache Software Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 23% of all known vulnerabilities).
Official description
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.
