vm2 before 3.11.7 Module Allowlist Bypass via Custom Resolver
Published Sep 17, 2026 · Updated Sep 17, 2026
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.
