CVE-2026-92941: Patriksimek VM2

Critical severity, CVSS 10.0. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Patriksimek VM2: from 3.11.3, before 3.11.7 (fixed in 3.11.7)
