Is localtunnel even maintained? Still has CRITICAL SECURITY VULNERABILITY (axios) from 2 years ago

Author: myarcanaCreated Oct 30, 2025Updated Nov 20, 2025

https://github.com/localtunnel/localtunnel/issues/632 2 years old issue pointing out the critical security vulnerabilit**ies** that localtunnel's axios version has: revealing confidential information on every request, enabling server-side request forgery (ssrf), and makes the server vulnerable to DoS attacks.

This affects the latest version of localtunnel (that everyone uses with npx localtunnel):

% tempdir="$(mktemp -d)" npm install localtunnel@"$(npx localtunnel --version)" --package-lock-only --prefix "$tempdir" && npm audit --prefix "$tempdir"
