VCID-ftjz-3fh5-j7dz Denial of Service in http-proxy Versions of `http-proxy` prior to 1.18.1 are vulnerable to Denial of Service. An HTTP request with a long body triggers an `ERR_HTTP_HEADERS_SENT` unhandled exception that crashes the proxy server. This is only possible when the proxy server sets headers in the proxy request using the `proxyReq.setHeader` function. For a proxy server running on `http://localhost:3000`, the following curl request triggers the unhandled exception: ```curl -XPOST http://localhost:3000 -d "$(python -c 'print("x"*1025)')"``` ## Recommendation Upgrade to version 1.18.1 or later GHSA-6x33-pw7p-hmpq
