vm2 is an open source vm/sandbox for Node.js. From 3.9.6 to 3.10.5, vm2's bridge exposes mutable proxies for real host-realm intrinsic prototypes and then forwards sandbox writes into the underlying host objects with otherReflectSet() and otherReflectDefineProperty(), which lets…

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…

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, NodeVM's builtin allowlist can be bypassed when the module builtin is allowed (including via the '*' wildcard). The module builtin exposes Node's Module._load(), which loads any module by name directly in the host…

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, a sandbox escape vulnerability in vm2 v3.10.5 allows any sandboxed code to crash the host Node.js process via a single Promise constructor that triggers an unhandled rejection propagating to the host. The fix for…

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()…

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.1, when a NodeVM is created with nesting: true, sandbox code can unconditionally require('vm2') regardless of the outer VM's require configuration — including require: false. With access to vm2, the sandbox constructs…

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…

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…

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM supports excluding public network builtins from the wildcard builtin option. With this configuration direct access to http, https, http2, net, dgram, tls, dns, and dns/promises is blocked. However,…

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, sandboxed code can call Buffer.alloc() with an arbitrary size to allocate memory directly on the host heap. Because Buffer.alloc is a synchronous C++ native call, vm2's timeout option cannot interrupt it. A single…

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, a sandbox boundary violation in vm2 allows host object identity to cross into the sandbox through host Promise resolution. When a host-side Promise that resolves to a host object is exposed to the sandbox, the value…

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM exposes some process-wide observability builtins when they are allowed through require.builtin. The diagnostics_channel, async_hooks, and perf_hooks builtins are not blocked by the dangerous builtin…

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, vm2's CallSite wrapper class (intended as a safe wrapper for V8's native CallSite) blocks getThis() and getFunction() to prevent host object leakage, but allows getFileName() to return unsanitized host absolute…

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…

vm2 is an open source vm/sandbox for Node.js. In vm2 for versions up to and including 3.9.19, Node.js custom inspect function allows attackers to escape the sandbox and run arbitrary code. This may result in Remote Code Execution, assuming the attacker has arbitrary code…

vm2 is an advanced vm/sandbox for Node.js. The library contains critical security issues and should not be used for production. The maintenance of the project has been discontinued. In vm2 for versions up to 3.9.19, `Promise` handler sanitization can be bypassed with the…

vm2 is a sandbox that can run untrusted code with Node's built-in modules. A sandbox escape vulnerability exists in vm2 for versions up to and including 3.9.17. It abuses an unexpected creation of a host object based on the specification of `Proxy`. As a result a threat actor…

vm2 is a sandbox that can run untrusted code with Node's built-in modules. In versions 3.9.17 and lower of vm2 it was possible to get a read-write reference to the node `inspect` method and edit options for `console.log`. As a result a threat actor can edit options for the…

vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Prior to version 3.9.15, vm2 was not properly handling host objects passed to `Error.prepareStackTrace` in case of unhandled async errors. A threat actor could bypass the sandbox protections…

The package vm2 before 3.9.10 are vulnerable to Arbitrary Code Execution due to the usage of prototype lookup for the WeakMap.prototype.set method. Exploiting this vulnerability leads to access to a host object and a sandbox compromise.

vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. In versions prior to version 3.9.11, a threat actor can bypass the sandbox protections to gain remote code execution rights on the host running the sandbox. This vulnerability was patched in…

This affects the package vm2 before 3.6.11. It is possible to trigger a RangeError exception from the host rather than the "sandboxed" context by reaching the stack call limit with an infinite recursion. The returned object is then used to reference the mainModule property of…

The package vm2 before 3.9.6 are vulnerable to Sandbox Bypass via direct access to host error objects generated by node internals during generation of a stacktraces, which can lead to execution of arbitrary code on the host machine.

This affects the package vm2 before 3.9.4 via a Prototype Pollution attack vector, which can lead to execution of arbitrary code on the host machine.
