CVE-2026-104849

Tinypool is a minimal Node.js worker thread pool implementation. Prior to 2.1.2, Tinypool reads filename from a caller-supplied options object in pool.runtask, options without requiring an own property, so a polluted Object.prototype.filename can replace the intended worker module. Applications a...

vm2: NodeVM nesting guard accepts array-shaped require and permits host RCE

Summary The NodeVM constructor computes hasRealRequireConfig using typeof requireOpts === 'object' && requireOpts !== null, so require: bypasses the guard intended to reject nesting without an explicit require configuration. makeResolverFromLegacyOptions then destructures the array to undefined...

vm2 crypto builtin loads attacker native code through setEngine

Summary vm2 3.11.6 exposes the host crypto module to a NodeVM when that single builtin is allowed. The module is presented through a read-only bridge, but its functions still execute with host-process authority. crypto.setEngine accepts a filesystem path and asks OpenSSL to dynamically load the...

CVE-2026-92954

A flaw was found in vm2. An attacker capable of running untrusted code within the sandbox can trigger a Denial of Service DoS by causing the host application process to terminate. This vulnerability exists because asynchronous operations Promises returned from the host environment are not properl...

ReflectiveDLLInjection

About Reflective DLL injection is a library injection technique in which the concept of reflective programming is employed to perform the loading of a library from memory into a host process. As such the library is responsible for loading itself by implementing a minimal Portable Executable PE fi...

CVE-2026-100722 vm2 before 3.12.2 Host Process Termination via Construct Trap

vm2 before 3.12.2 does not apply host-side Promise rejection handling in the sandbox-to-host construct trap. In BaseHandler, the apply trap calls markHostPromiseHandled on the returned value, but the adjacent construct path returns the result of Reflect.construct without the same sanitization. If...

CVE-2026-61670: Invocation of Process Using Visible Sensitive Information

microsandbox is an easy, fast, local-first microVM runtime and library. Prior to 0.5.10, sdk/rust/lib/runtime/spawn.rs serializes NetworkConfig secret values into the --network-config argument and passes per-sandbox secrets through repeated --env arguments accepted by crates/cli/lib/sandboxcmd.rs...

Protection Mechanism Failure

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 Protection Mechanism Failure in the node:sqlite module exposure within the sandbox environment when certain builtins are permitted. An attacker can...

Uncaught Exception

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 Uncaught Exception in the handling of Promises returned from the host realm into the sandbox. An attacker can cause the host process to terminate...

Process Control

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 Process Control in the crypto.setEngine function. An attacker can execute arbitrary native code in the host process by supplying a path to a maliciou...

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...
