Technical details
The vulnerability is a server-side request forgery (SSRF) in the SSL certificate fetching logic that fails to properly validate destination URLs. By crafting malicious userinfo in URLs and setting fetch_ssl_certificate=true, attackers bypass destination checks and force SSLCertificate.from_url() to connect to internal addresses on port 443, allowing reachability probing and certificate information disclosure.
