CVE-2026-92953

A flaw was found in vm2. The sandbox fails to properly isolate host object structures from untrusted code running inside the virtual machine. An attacker can exploit this issue by manipulating object prototype chains to modify shared host prototypes, resulting in prototype pollution the...

CVE-2026-100722

A flaw was found in vm2. An attacker who can execute untrusted code within the sandbox can trigger an unhandled error by instantiating host-provided functions that return a rejected asynchronous operation Promise. Due to missing error handling in the sandbox-to-host object construction trap, the...

Arbitrary Code Injection

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 Arbitrary Code Injection in the handling of rejected host Promises via call or apply indirection. An attacker can execute arbitrary commands with the...

Modification of Assumed-Immutable Data (MAID)

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 Modification of Assumed-Immutable Data MAID in the Object.getOwnPropertyDescriptor or lookupSetter process. An attacker can modify properties that we...

CVE-2026-85165 n8n before 2.36.2 Expression Sandbox Bypass via SpreadElement

n8n versions before 2.36.2 contain an expression sandbox bypass vulnerability where free identifiers in spread, computed-key, switch-case, or class-extension positions resolve against process globals. Authenticated users with workflow-edit permission can mutate host objects through expression...

EUVD-2026-60460

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.6, handleException in lib/setup-sandbox.js sanitizes SuppressedError.error, SuppressedError.suppressed, and AggregateError.errors but does not sanitize Error.cause, allowing sandbox code to obtain a powerful host object such as process...

Arbitrary Code Injection

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 Arbitrary Code Injection through the handleException function, which fails to sanitize the .cause property of errors. An attacker can gain access to...

PT-2026-76816

Name of the Vulnerable Software and Affected Versions vm2 versions prior to 3.11.6 Description In the handleException function within lib/setup-sandbox.js, the software fails to sanitize the Error.cause property introduced in ES2022. While the function recursively sanitizes SuppressedError.error,...

CVE-2026-47209 vm2: Bridge Proxy set trap ignores receiver parameter, enabling host object property injection via prototype chain

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, the BaseHandler.set trap in bridge.js line 1231 ignores the receiver parameter and unconditionally writes to the host target object. Per the Proxy set trap specification, when receiver !== proxy e.g., when a child object...

CVE-2026-44000

A flaw was found in vm2 before 3.11.0. Host-side Promises that resolve to host objects deliver values to sandbox .then callbacks without cross-realm conversion ensureThis instead of from/proxy wrapping, allowing sandbox code to interact with host objects directly. Fixed in 3.11.0...

CVE-2026-43997

A flaw was found in vm2 before 3.11.0, a Node.js sandbox library. Sandboxed code can obtain the host Object e.g. via HostObject.getOwnPropertySymbols and Symbolnodejs.util.inspect.custom, bypassing isolation and enabling arbitrary code execution on the host...

CVE-2026-44008

A flaw was found in vm2 before 3.11.2. The neutralizeArraySpeciesBatch method can invoke host-side getters on array prototypes, exposing host objects and the host Function into the sandbox for escape and arbitrary command execution. Fixed in 3.11.2...

Improperly Controlled Modification of Dynamically-Determined Object Attributes

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 Improperly Controlled Modification of Dynamically-Determined Object Attributes via the BaseHandler.set trap in lib/bridge.js. An attacker can mutate...
