Exposure of Resource to Wrong Sphere

Overview org.webjars.npm: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...

CVE-2026-100723 vm2 before 3.12.2 Memory Disclosure via zlib Buffer Pool

vm2 before 3.12.2 does not apply its Buffer backing-store ownership invariant byteOffset === 0 and buffer.byteLength === length to Buffers returned from host builtin modules. When an application explicitly exposes Node's zlib module through NodeVM's builtin allowlist require: builtin: 'zlib' ,...

CVE-2026-100723

The vm2 library before version 3.12.2 is vulnerable to a memory disclosure and corruption issue due to a failure in applying Buffer backing-store ownership invariants for host builtin modules. When an application exposes the zlib module via NodeVM's builtin allowlist, zlib.deflateSync can return ...
