A\u00a0request 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.\n\nCredit:\n\nZiyue (reporter)\nshreemaan-abhishek (coordinator)\nshreemaan-abhishek (remediation developer)\n\nReferences:\n\nhttps://apisix.apache.org\nhttps://www.cve.org/CVERecord?id=CVE-2026-94269\n\n",
