CVE-2026-43999 [CRITICAL] CWE-863 CVE-2026-43999: vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, NodeVM's builtin allowlist can be byp 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 context, completely bypassing vm2's builtin restriction. This allows san

CVE-2023-37903 [CRITICAL] CWE-78 CVE-2023-37903: vm2 is an open source vm/sandbox for Node.js. In vm2 for versions up to and including 3.9.19, Node.j 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 execution primitive inside the context of vm2 sandbox. There are no patches an

CVE-2026-22709 [CRITICAL] CWE-94 CVE-2026-22709: vm2 is an open source vm/sandbox for Node.js. In vm2 prior to version 3.10.2, `Promise.prototype.the vm2 is an open source vm/sandbox for Node.js. In vm2 prior to version 3.10.2, `Promise.prototype.then` `Promise.prototype.catch` callback sanitization can be bypassed. This allows attackers to escape the sandbox and run arbitrary code. In lib/setup-sandbox.js, the callback function of `localPromise.prototype.then` is sanitized, but `globalPromise.p

Prior to 3.11.2, the new method neutralizeArraySpeciesBatch works with objects from the other side but can call into this side via getter on the array prototype exposing objects of the wrong side into the sandbox. This can be used to get host objects and get the host Function object. This allows attack

CVE-2026-45411 [CRITICAL] CWE-668 CVE-2026-45411: vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.3, it is possible to catch a host except 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 the runtime and passed to the yield* iterator as the

CVE-2026-43998 [HIGH] CWE-59 CVE-2026-43998: vm2 is an open source vm/sandbox for Node.js. In 3.10.5, NodeVM's require.root path restriction can 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 dereference symlinks) but module loading uses Node's native

CVE-2026-47140 [CRITICAL] CWE-693 NodeVM builtin denylist bypass via process and inspector/promises allows host code execution NodeVM builtin denylist bypass via process and inspector/promises allows host code execution ## Summary `NodeVM` blocks several dangerous Node.js builtins such as `module`, `worker_threads`, `cluster`, `vm`, `repl`, and `inspector`. However, the denylist misses `process` and `inspector/promises`. Both can be used from sandboxed code to reach host-side execution primit

CVE-2026-47137 [CRITICAL] CWE-913 vm2 has a CVE-2023-37903 patch bypass: nesting:true without explicit require still allows full RCE vm2 has a CVE-2023-37903 patch bypass: nesting:true without explicit require still allows full RCE ## Summary The fix for GHSA-8hg8-63c5-gwmx (CVE-2023-37903) introduced a check in `nodevm.js` line 263 that blocks the combination `nesting: true` + `require: false`. However, the check uses strict equality (`options.require === false`), which is trivially bypassed
