CVE-2026-92963

vm2 versions before 3.11.2 fail to properly restrict access to the VM2INTERNALSTATEDONOTUSEORPROGRAMWILLFAIL global variable. Attackers can access this internal state object through globalThis to retrieve sensitive sandbox internals...

CVE-2026-92961

vm2 before 3.11.6 fails to enforce bufferAllocLimit on ArrayBuffer, SharedArrayBuffer, and TypedArray constructors, allowing attackers to allocate arbitrary host memory. Attackers can bypass the buffer allocation cap by using these V8 intrinsics to exhaust host process memory and trigger...

CVE-2026-92957

vm2 through 3.11.6 does not normalize node:-prefixed builtin specifiers when evaluating user-supplied negative deny entries in a NodeVM wildcard require policy. Although NodeVM strips the node: prefix during require resolution, negative wildcard entries are matched by exact string comparison...

CVE-2026-92956

vm2 versions 3.10.1 through 3.11.6 contain a sandbox escape reachable from a default new VM sandbox when running on Node.js 26. WebAssembly.compileStreaming and WebAssembly.instantiateStreaming can produce a raw host-realm Promise that rejects with a host-realm error object; by controlling...

CVE-2026-92958

vm2 through 3.11.6 contains a builtin-module denylist bypass in NodeVM. When the embedder uses the builtin wildcard together with negative entries e.g. require: builtin: '', '-fs', '-childprocess' , negative entries are matched by exact module name in lib/builtin.js, so -fs removes only the built...

CVE-2026-92953

vm2 versions from 3.11.0 before 3.11.8 fail to protect host TypedArray and ArrayBuffer prototypes from sandbox mutation. Attackers can use prototype-walking primitives to reach and modify host Uint8Array.prototype, %TypedArray%.prototype, and ArrayBuffer.prototype, causing host-created typed arra...

CVE-2026-92954

vm2 is a sandbox library for running untrusted JavaScript in Node.js. In versions = 3.10.0 and = 3.11.7, Promises returned from the host realm into the sandbox are not marked as handled at the bridge boundary; only Promises created inside the sandbox are wrapped with a rejection-swallowing handle...

CVE-2026-92955

vm2 before 3.11.8 contains a sandbox escape vulnerability in NodeVM that allows attackers to access the host proto getter/setter through console.stdout and console.stderr. Attackers can overwrite EventEmitter.prototype.emit and trigger process events to execute code with process context, bypassin...

CVE-2026-92947

vm2 before 3.11.7 exposes Node's shared Buffer pool to sandboxed code, allowing disclosure of host memory used by Buffer.from, Buffer.concat, and related allocations. Sandboxed code can read and write to host-realm buffers by acquiring ArrayBuffers from small allocations, leading to sensitive dat...

CVE-2026-92948

vm2 versions = 3.9.6 and therefore executes arbitrary JavaScript in an unrestricted host Node process outside the NodeVM sandbox. Fixed in vm2 3.11.7...

CVE-2026-92950

vm2 before 3.11.7 contains a sandbox escape vulnerability in the CLI tool that allows attackers to execute arbitrary code in the host Node.js process. Attackers can supply a malicious script file to the vm2 CLI that uses requirefilename to re-execute itself in the host realm, bypassing sandbox...

CVE-2026-92952

vm2 versions 3.11.4 through 3.11.6 incompletely filter Node.js registered internal symbols across the sandbox boundary. The extraction filters in lib/setup-sandbox.js and the cross-realm symbol checks and write traps in lib/bridge.js use a fixed list of known dangerous registered symbols that omi...

CVE-2026-92951

vm2 before 3.11.7 contains an incorrect authorization vulnerability in the external package allowlist check that uses non-exact substring matching instead of full package-name boundary validation. Attackers can bypass the allowlist by requiring a colliding package name that contains an allowliste...

CVE-2026-92949

vm2 versions from 3.9.6 before 3.11.7 fail to properly restrict access to accessor properties on frozen objects, allowing sandboxed scripts to bypass vm.freeze and vm.readonly protections. Attackers can use Object.getOwnPropertyDescriptor or lookupSetter to extract and invoke host object setters...

CVE-2026-92941

vm2 versions from 3.11.3 before 3.11.7 expose the host tls module to NodeVM sandbox code, allowing attackers to call tls.setDefaultCACertificates and replace process-wide certificate authorities. Attackers with access to allowed tls and url builtins can use URLSearchParams to create host-realm...

CVE-2026-92942

vm2 before 3.11.7 affected versions = 3.11.6 does not enforce the VM timeout option on code executed outside the synchronous VMrun call. The timeout only wraps the single call to runScript via doWithTimeout in lib/vm.js, and FinalizationRegistry and WeakRef are exposed to sandboxed code unmodifie...

CVE-2026-92940

vm2 versions 3.11.3 through 3.11.6 expose the host process's real https.globalAgent to sandboxed code when a NodeVM is explicitly configured to allow require'https'. The builtin loader wraps host modules in a read-only proxy, but method calls such as Agent.prototype.on are forwarded to the...

CVE-2026-92944

vm2 versions 3.10.2 through 3.11.6 contain a sandbox escape vulnerability on Node.js 26 where Promise.prototype.finally bypasses vm2's wrapper protections due to a stale PromiseThenLookupChain protector in V8 14.6. Attackers can exploit this by creating an async function that returns a Promise wi...

CVE-2026-92946

vm2 before 3.11.7 contains a remote code execution vulnerability when require.external is enabled without an explicit require.root that excludes nodemodules. Sandboxed code can require vm2's own package, instantiate an unrestricted NodeVM instance, and execute arbitrary host OS commands via...

CVE-2026-92945

vm2 before 3.11.7 contains a module allowlist bypass vulnerability in isPathAllowedForModule that uses raw string prefix matching instead of boundary-anchored comparison. Attackers can reach non-allowlisted packages sharing a prefix with allowlisted modules by performing relative requires from...
