What is CVE-2026-124680?

An interpretation conflict vulnerability exists within Apache APISIX that may lead to incorrect authorization. An unauthenticated client can leverage this issue to access protected upstream paths governed by a route-level authorization plugin when another route lacking authentication exists on the same upstream. This vulnerability is exacerbated in situations where the upstream fails to collapse encoded dot segments properly, allowing unauthorized access to sensitive resources. Users should upgrade their installations to Apache APISIX version 3.20.0 or later to mitigate this risk.

Affected Version(s)

Apache APISIX 0.9 <= 3.19.0
