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-2026-92961

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...

GHSA-V836-6XW4-9CX3 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...
