GHSA-98xx-8mx4-x7cm: vm2 (CVE-2026-92941)

Package	Ecosystem	Affected	Fixed in
vm2	npm	>=3.11.3, <3.11.7	3.11.7

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GHSA-98xx-8mx4-x7cm affects the npm package vm2 in versions 3.11.3 up to but not including 3.11.7, with 3.11.7 listed as the fix. The source says that a NodeVM configured with the tls and url builtins can call the host tls function that replaces the default certificate authorities trusted by later host-side TLS clients. An attacker who can submit code to such a sandbox could make host HTTPS clients trust an attacker-controlled CA, which could enable credential theft or response tampering when they can also influence the destination or network path. Upgrade to vm2 3.11.7 or later.
