CVE-2026-92941 is rated critical with a CVSS v3.1 base score of 10.0. Per its scoring, it can be exploited over the network, without authentication, without any user interaction.
Vulnerability description
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.
