Title
Apache APISIX: Cross-user response poisoning in serverless plugins
Summary
Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') vulnerability in Apache APISIX. An attacker could make other clients receive attacker-chosen or other users' responses on serverless-plugin routes. This issue affects Apache APISIX: from 2.12.0 through 3.17.0. Users are recommended to upgrade to version 3.18.0, which fixes the issue.
