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.\n\n\n\nUsers are recommended to upgrade to version 3.19.0, which fixes the issue.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "2.14.1"}, {"last_affected": "2.14.1"}]}]}], "references": [{"type": "WEB", "url": "https://lists.apache.org/thread.html/6p7glm8jtkjrn12t7z2ybn6bplm22tns"}]}
