Key facts

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.

Users are recommended to upgrade to version 3.19.0, which fixes the issue.
