GHSA-7Q3F-WX44-378M vm2: External module allowlist uses a raw prefix test, so a prefix-sharing sibling package is treated as allowlisted

Summary isPathAllowedForModule decides whether a resolved path belongs to an allowlisted external module using a raw string prefix test. nodemodules/foo2 starts with nodemodules/foo, so a package whose name merely shares a prefix with an allowlisted one is treated as being inside it, and a relati...

vm2 isPathAllowedForModule Unauthorized Access

The vulnerability of the isPathAllowedForModule function in the vm2 library of the NPM package manager is related to an incorrect restriction on path names for directories. Exploiting this vulnerability could allow a remote attacker to gain unauthorized access to protected information...

CVE-2026-92945

A flaw was found in vm2. This vulnerability allows an attacker to bypass the module allowlist, a security feature designed to restrict access to certain software modules. The flaw occurs due to an incorrect string comparison method used in the isPathAllowedForModule function. By exploiting this, ...

Directory Traversal

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Directory Traversal via the isPathAllowedForModule function. An attacker can access non-allowlisted modules by exploiting prefix matching in module...
