Recommendation: Monitor — no exploitation signal at the moment.
client-certificate-auth is middleware for Node.js implementing client SSL certificate authentication/authorization. Versions 0.2.1 and 0.3.0 of client-certificate-auth contain an open redirect vulnerability. The middleware unconditionally redirects HTTP requests to HTTPS using the unvalidated Host header, allowing an attacker to redirect users to arbitrary domains. This vulnerability is fixed in 1.0.0.
