CVE-2026-100721

vm2 before 3.12.2 contains an authorization bypass in the NodeVM external-module resolver. When an embedder configures require.external with a custom resolver and context: 'host', LegacyResolver.customResolve in lib/resolver-compat.js records the resolved module directory in this.externals as new...

CVE-2026-100723 vm2 before 3.12.2 Memory Disclosure via zlib Buffer Pool

vm2 before 3.12.2 does not apply its Buffer backing-store ownership invariant byteOffset === 0 and buffer.byteLength === length to Buffers returned from host builtin modules. When an application explicitly exposes Node's zlib module through NodeVM's builtin allowlist require: builtin: 'zlib' ,...

CVE-2026-100721

The vm2 library (versions before 3.12.2 ) contains an authorization bypass in the NodeVM external-module resolver. When an embedder uses a custom resolver with context: 'host', the LegacyResolver.customResolve function in lib/resolver-compat.js fails to include a path separator or end-of-string b...

CVE-2026-93605

A flaw was found in vm2. The sandbox environment fails to restrict access to the childprocess module, which handles system command execution. In environments configured to allow built-in modules, an attacker capable of running untrusted code within the sandbox can load this module to break...

Protection Mechanism Failure

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 Protection Mechanism Failure via sanitizeCryptoModule in lib/builtin.js, where a NodeVM that allowlists the crypto builtin exposes crypto.setFips...

Improper Control of Dynamically-Managed Code Resources

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 Improper Control of Dynamically-Managed Code Resources via the NodeVM builtin module denylist in lib/builtin.js, which omits childprocess from...

CVE-2026-93605

vm2 NodeVM versions before 3.12.1 contain a sandbox escape vulnerability where the DANGEROUSBUILTINS denylist omits childprocess despite blocking other host-spawning modules. Attackers can require childprocess and execute arbitrary commands on the host system when NodeVM is configured with...

CVE-2026-93605 vm2 NodeVM before 3.12.1 Remote Code Execution via child_process

vm2 NodeVM versions before 3.12.1 contain a sandbox escape vulnerability where the DANGEROUSBUILTINS denylist omits childprocess despite blocking other host-spawning modules. Attackers can require childprocess and execute arbitrary commands on the host system when NodeVM is configured with...

CVE-2026-93605

vm2 NodeVM versions before 3.12.1 contain a sandbox escape vulnerability rated CVSS 10.0 (Critical) . The DANGEROUS_BUILTINS denylist omits child_process despite blocking other host-spawning modules. When NodeVM is configured with builtin:['*'] or an explicit child_process allowance, an attacker ...

CVE-2026-93604 vm2 3.11.8 Sandbox Escape via crypto.setFips

vm2 through 3.12.0 exposes Node.js's crypto.setFips function to untrusted guest code when an embedder explicitly allowlists the crypto builtin for a NodeVM require.builtin: 'crypto'. The builtin sanitizer sanitizeCryptoModule in lib/builtin.js replaces crypto.setEngine but leaves crypto.setFips...

CVE-2026-93604 vm2 3.11.8 Sandbox Escape via crypto.setFips

vm2 through 3.12.0 exposes Node.js's crypto.setFips function to untrusted guest code when an embedder explicitly allowlists the crypto builtin for a NodeVM require.builtin: 'crypto'. The builtin sanitizer sanitizeCryptoModule in lib/builtin.js replaces crypto.setEngine but leaves crypto.setFips...

CVE-2026-93604: Improper Access Control

vm2 through 3.12.0 exposes Node.js's crypto.setFips function to untrusted guest code when an embedder explicitly allowlists the crypto builtin for a NodeVM require.builtin: 'crypto'. The builtin sanitizer sanitizeCryptoModule in lib/builtin.js replaces crypto.setEngine but leaves crypto.setFips...

CVE-2026-93606: Protection Mechanism Failure

vm2 npm versions 3.12.0 and earlier contain a sandbox escape in VM and NodeVM. When an embedder exposes a host API that returns a host-realm Promise, the bridge's rejection sanitizer hostPromiseSanitizeReject / makeSanitizedPromiseCallback / normalizeHostPromiseCallbacks in lib/bridge.js only wra...

Improper Control of Dynamically-Managed Code Resources

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules.
