[Security] Bump http-proxy from 1.18.0 to 1.18.1

[dependabot-preview]

Bumps http-proxy from 1.18.0 to 1.18.1. This update includes a security fix.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

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

Affected versions: < 1.18.1
