CVE-2026-93605

vm2 NodeVM versions before 3.12.1 contain a sandbox escape vulnerability rated CVSS 10.0 (Critical) . The DANGEROUS_BUILTINS denylist omits child_process despite blocking other host-spawning modules. When NodeVM is configured with builtin:['*'] or an explicit child_process allowance, an attacker ...

CVE-2026-93604

vm2 through 3.12.0 allows untrusted guest code to cross the NodeVM isolation boundary when the embedder allowlists the crypto builtin. The builtin sanitizer in lib/builtin.js replaces crypto.setEngine but leaves crypto.setFips callable, and the readonly wrapper does not localize side effects of f...

CVE-2026-93603 vm2 before 3.12.1 Sandbox Escape RCE via Non-Strict Host Function

vm2 through 3.12.0 fixed in 3.12.1 does not correctly handle a nullish this receiver in the apply trap of its bridge lib/bridge.js: when sandboxed code calls a host-provided non-strict sloppy-mode function without a receiver — e.g. fn, a detached method, fn.call, fn.applyundefined, Reflect.applyf...

CVE-2026-93603

vm2 (Node.js sandbox library) through 3.12.0 is vulnerable to a complete sandbox escape due to incorrect handling of a nullish this receiver in the apply trap of its bridge (lib/bridge.js). When sandboxed code invokes a host-provided non-strict (sloppy-mode) function without a receiver (e.g., fn(...

CVE-2026-93605: Protection Mechanism Failure

vm2 NodeVM versions before 3.12.1 contain a sandbox escape vulnerability where the DANGEROUSBUILTINS denylist omits childprocess despite blocking other host-spawning modules. Attackers can require childprocess and execute arbitrary commands on the host system when NodeVM is configured with...

CVE-2026-93606: Protection Mechanism Failure

vm2 npm versions 3.12.0 and earlier contain a sandbox escape in VM and NodeVM. When an embedder exposes a host API that returns a host-realm Promise, the bridge's rejection sanitizer hostPromiseSanitizeReject / makeSanitizedPromiseCallback / normalizeHostPromiseCallbacks in lib/bridge.js only wra...

CVE-2026-92962

A flaw was found in vm2, a sandbox for running untrusted JavaScript. Malicious code running within the sandbox can exploit a weakness in how stack traces are handled. By manipulating the Array.prototype, an attacker can observe and intercept individual lines of stack traces, leading to an...

CVE-2026-92945

A flaw was found in vm2. This vulnerability allows an attacker to bypass the module allowlist, a security feature designed to restrict access to certain software modules. The flaw occurs due to an incorrect string comparison method used in the isPathAllowedForModule function. By exploiting this, ...

CVE-2026-92963

A flaw was found in vm2. An attacker can exploit this vulnerability by improperly accessing the VM2INTERNALSTATEDONOTUSEORPROGRAMWILLFAIL global variable through globalThis. This allows the attacker to retrieve sensitive internal information from the sandbox environment, leading to information...

CVE-2026-47683

A flaw was found in vm2, an open-source virtual machine VM sandbox for Node.js. This vulnerability allows malicious code running within the sandbox to bypass the configured memory allocation limit. By crafting specific calls to Buffer.concat or Buffer.from with attacker-controlled lengths, the...

CVE-2026-92942

A flaw was found in vm2. Sandboxed code can bypass the configured timeout mechanism by using the FinalizationRegistry feature. This allows an attacker to execute a busy loop in a cleanup callback, which is invoked outside the timeout accounting. Consequently, this can block the host event loop...
