vm2 versions from 3.11.3 before 3.11.7 expose the host tls module to NodeVM sandbox code, allowing attackers to call tls.setDefaultCACertificates() and replace process-wide certificate authorities. Attackers with access to allowed tls and url builtins can use URLSearchParams to create host-realm arrays and manipulate the TLS trust store, enabling subsequent host HTTPS clients to accept attacker-controlled certificates.
