CVE-2026-92959: Protection Mechanism Failure

vm2 before 3.11.8 does not fully enforce the allowAsync: false option in VM and NodeVM. While localPromise.prototype.then is replaced with a handler that throws 'Async not available', the sandbox's Promise static methods Promise.resolve, Promise.all, Promise.race, Promise.any, and...

Name of the Vulnerable Software and Affected Versions vm2 versions 3.9.6 through 3.11.6 Description A NodeVM builtin allowlist bypass allows a sandbox escape on Node.js 24 and newer when the embedder explicitly allows the node:test builtin. On Node.js 24+, module.builtinModules exposes the...

CVE-2026-92963: Undefined Security Weakness

vm2 versions before 3.11.2 fail to properly restrict access to the VM2INTERNALSTATEDONOTUSEORPROGRAMWILLFAIL global variable. Attackers can access this internal state object through globalThis to retrieve sensitive sandbox internals...

CVE-2026-92951: Use of Incorrectly-Resolved Name or Reference

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 allowliste...

CVE-2026-92937: Improper Control of Generation of Code

vm2 3.11.6 is vulnerable to a sandbox escape leading to remote code execution in the host Node.js process. The fix for GHSA-m283-3h24-438v is incomplete: the bridge gate at lib/bridge.js:1624 identity-checks only the direct call target when deciding whether to rebuild/sanitise a rejected host...

CVE-2026-92956: Protection Mechanism Failure

vm2 versions 3.10.1 through 3.11.6 contain a sandbox escape reachable from a default new VM sandbox when running on Node.js 26. WebAssembly.compileStreaming and WebAssembly.instantiateStreaming can produce a raw host-realm Promise that rejects with a host-realm error object; by controlling...

CVE-2026-92936: Generation of Error Message Containing Sensitive Information

vm2 versions 3.11.0 through 3.11.6 leak absolute host filesystem paths to sandboxed code through error stack formatting. Attacker-supplied code can force the host-realm source transformer to throw a SyntaxError for example by calling eval with malformed source and then read the error's .stack...

CVE-2026-92939: Process Control

vm2 3.11.3 through 3.11.6 exposes the host Node.js crypto module to a NodeVM sandbox when the crypto builtin is allowed. The module is presented via a recursive read-only proxy, but its callable exports still execute with host-process authority. Sandboxed JavaScript can therefore call...

CVE-2026-92949: Modification of Assumed-Immutable Data (MAID)

vm2 versions from 3.9.6 before 3.11.7 fail to properly restrict access to accessor properties on frozen objects, allowing sandboxed scripts to bypass vm.freeze and vm.readonly protections. Attackers can use Object.getOwnPropertyDescriptor or lookupSetter to extract and invoke host object setters...

CVE-2026-92952: Incorrect Resource Transfer Between Spheres

vm2 versions 3.11.4 through 3.11.6 incompletely filter Node.js registered internal symbols across the sandbox boundary. The extraction filters in lib/setup-sandbox.js and the cross-realm symbol checks and write traps in lib/bridge.js use a fixed list of known dangerous registered symbols that omi...

CVE-2026-92960: Exposure of Sensitive Information to an Unauthorized Actor

vm2 before 3.11.6 fails to restrict access to os and dns builtins under the builtin: '' configuration, allowing sandbox code to read host process identity and network topology. Attackers can invoke dns.setServers to hijack the host process DNS resolver globally, redirecting all subsequent host DN...

CVE-2026-92948: Protection Mechanism Failure

vm2 versions = 3.9.6 and = 3.11.6 are affected by a NodeVM builtin allowlist bypass that permits a sandbox escape on Node.js 24 and newer when the embedder explicitly allows the node:test builtin e.g. require: builtin: 'node:test' . On Node.js 24+, module.builtinModules exposes the scheme-only ke...

CVE-2026-92950: Insecure Default Variable Initialization

vm2 before 3.11.7 contains a sandbox escape vulnerability in the CLI tool that allows attackers to execute arbitrary code in the host Node.js process. Attackers can supply a malicious script file to the vm2 CLI that uses requirefilename to re-execute itself in the host realm, bypassing sandbox...
