CVE-2026-47135

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, Symbol.for override in setup-sandbox.js only intercepts 2 of 9 dangerous Node.js cross-realm symbols. Combined with the bridge's set/defineProperty/deleteProperty traps having no isDangerousCrossRealmSymbol key check, sandbox...

CVE-2026-47131

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, by combining Buffer.call.call.lookupGetter, Buffer, "proto", Buffer.call.call.lookupSetter, Buffer, "proto", and Node.js's ERRINVALIDARGTYPE Error, the host's TypeError constructor can be obtained, which allows the escape from...

CVE-2026-47208 vm2: Sandbox Breakout Using Promise Species

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, VM2 suffers from a sandbox breakout vulnerability. This allows attackers to write code which can escape from the VM2 sandbox and execute arbitrary commands on the host system. This issue has been patched in version 3.11.4...

CVE-2026-47140 vm2: NodeVM builtin denylist bypass via process and inspector/promises allows host code execution

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM blocks several dangerous Node.js builtins such as module, workerthreads, cluster, vm, repl, and inspector. However, the denylist misses process and inspector/promises. Both can be used from sandboxed code to reach...

CVE-2026-47131

vm2 prior to 3.11.4 contains a sandbox escape: by using Buffer.call.call with {}.lookupGetter /lookupSetter and Node.js ERR_INVALID_ARG_TYPE, an attacker can obtain the host TypeError constructor and break out of the sandbox, enabling arbitrary code execution. The issue is fixed in vm2 v3.11.4. R...

CVE-2026-44003

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, vm2's code transformer has a performance optimization that skips AST analysis when the code does not contain catch, import, or async keywords. This fast-path bypass allows sandboxed code to directly access the internal...

CVE-2026-44009

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.2, This vulnerability is fixed in 3.11.2...

Incomplete List of Disallowed Inputs

Overview org.webjars.npm:vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs via the builtin allowlist handling in lib/builtin.js. An attacker can reach host code by requiri...

Improperly Controlled Modification of Dynamically-Determined Object Attributes

Overview org.webjars.npm:vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes via the BaseHandler.set trap in lib/bridge.js. An...

Incomplete List of Disallowed Inputs

Overview org.webjars.npm:vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs through Symbol.for handling in lib/setup-sandbox.js and the bridge write traps in lib/bridge.js...

vm2 has a Sandbox Escape issue

Summary By combining Buffer.call.call.lookupGetter, Buffer, "proto", Buffer.call.call.lookupSetter, Buffer, "proto", and Node.js's ERRINVALIDARGTYPE Error, the host's TypeError constructor can be obtained, which allows the escape from the sandbox. This allows attackers to run arbitrary code. PoC ...

CVE-2026-24118

A flaw was found in vm2, an open-source sandbox for Node.js. This sandbox breakout vulnerability allows attackers to write malicious code that can escape the vm2 sandbox. Successful exploitation enables the execution of arbitrary commands on the host system, leading to critical system compromise...

CVE-2026-43998

vm2 is an open source vm/sandbox for Node.js. In 3.10.5, NodeVM's require.root path restriction can be bypassed using filesystem symlinks, allowing sandboxed code to load modules from outside the allowed root directory in host context. Because path validation uses path.resolve which does not...

CVE-2026-43997

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, it is possible to obtain the host Object. There are various ways to use the host Object, to escape the sandbox, one example would be using HostObject.getOwnPropertySymbols to obtain Symbolnodejs.util.inspect.custom. This vulnerability...

CVE-2026-44005

The CVE-2026-44005 entry concerns vm2, a Node.js sandbox library. From versions 3.9.6 through 3.10.5, vm2’s bridge exposes mutable host-intrinsic prototypes and forwards sandbox writes into host objects, enabling attacker-controlled code inside a sandbox (default VM or inherited NodeVM) to mutate...

CVE-2026-45411 vm2: Sandbox Breakout Using Async Generator

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.3, it is possible to catch a host exception using the yield expression inside an async generator. When the generator is closed using the return function, the value is awaited on and exceptions thrown in the then call will be caught by th...
