CVE-2026-92951 Details
Description
vm2 before 3.11.7 contains an incorrect authorization vulnerability in the external package allowlist check that uses non-exact substring matching instead of full package-name boundary validation. Attackers can bypass the allowlist by requiring a colliding package name that contains an allowlisted package substring, causing vm2 to load and execute unauthorized host packages in the host context.
A vulnerability exists in vm2 versions through 3.11.6, where the external package allowlist check in the 'NodeVM' component incorrectly authorizes packages. The flaw arises because the allowlist uses non-exact substring matching instead of validating full package names. This allows attackers to bypass the allowlist by requiring a package name that collides with an allowlisted substring. As a result, vm2 may load and execute unauthorized host packages in the host context, potentially leading to execution of malicious code.
Users can upgrade to vm2 version 3.11.7 or later, where this vulnerability has been patched.
