GHSA-3VGF-8M4Q-Q4QR vm2: Default VM can mutate host TypedArray and ArrayBuffer intrinsics after the host-prototype pollution fix

Summary vm2's current host-intrinsic prototype protection is incomplete. The fix for GHSA-vwrp-x96c-mhwq blocks sandbox writes into classic host intrinsics such as Object.prototype, Array.prototype, and Function.prototype, but current head still lets sandbox code in a default VM reach and mutate...

GHSA-R9W8-H9R3-54W4 devalue: Custom ArrayBuffer revivers can bypass typed-array allocation validation

Under very specific circumstances, parse could create massive ArrayBuffers with very small input. This required a malformed ArrayBuffer custom reviver...

Exposure of Resource to Wrong Sphere

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 Exposure of Resource to Wrong Sphere via the bufferFrom and related Buffer factory functions in lib/setup-sandbox.js, where Node.js serves small...

The vulnerabilities of ArrayBuffer, SharedArrayBuffer, and TypedArray functions in the NPM package manager’s vm2 library allow attackers to compromise the accessibility of protected information.

The vulnerability of the ArrayBuffer, SharedArrayBuffer, and TypedArray functions in the vm2 package manager’s NPM library is related to the unlimited distribution of resources when processing the bufferAllocLimit parameter. Exploiting this vulnerability could allow an attacker to compromise the...

CVE-2026-92708

Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't sufficient for the job. In versions 5.1.0 through 5.9.2, stringify and uneval functions serialize a typed array by emitting its entire backing ArrayBuffer rather than only the view, so serializing...

CVE-2026-92708 devalue: Cross-request process memory disclosure in devalue when `stringify` / `uneval` serialize Node Buffers

Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't sufficient for the job. In versions 5.1.0 through 5.9.2, stringify and uneval functions serialize a typed array by emitting its entire backing ArrayBuffer rather than only the view, so serializing...

Improper Control of Dynamically-Managed Code Resources

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 Improper Control of Dynamically-Managed Code Resources through the mutation of TypedArray and ArrayBuffer prototypes. An attacker can alter the...

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...

vm2 has Memory Exhaustion DoS via bufferAllocLimit Bypass

Summary: The bufferAllocLimit defense GHSA-6785-pvv7-mvg7 can be completely bypassed using ArrayBuffer, SharedArrayBuffer, or any TypedArray constructor. These allocate identical host-process RSS through the same V8/libuv C++ allocation path as Buffer.alloc but are not subject to the size cap...
