CVE-2026-47683

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.6, the bufferAllocLimit enforcement in lib/setup-sandbox.js does not cover Buffer.concatlist, totalLength or Buffer.fromarrayLike with an attacker-controlled length, allowing sandbox code to perform large synchronous host external-memory...

vm2's bufferAllocLimit cap bypassed by Buffer.concat and Buffer.from arrayLike

Summary vm2 bufferAllocLimit cap bypassed by Buffer.concat and Buffer.from arrayLike The bufferAllocLimit option introduced in 3.11.0 GHSA-6785-pvv7-mvg7 caps host-side Buffer allocations driven by sandbox code, the way embedders opt into timeout. The cap wraps Buffer.alloc, Buffer.allocUnsafe,...

CVE-2024-21896

A flaw was found in Node.js. The permission model protects itself against path traversal attacks by calling path.resolve on any paths given by the user. If the path is to be treated as a buffer, the implementation uses Buffer.from to obtain a buffer from the result of path.resolve. By...

The permission model protects itself against path traversal attacks by calling path.resolve on any paths given by the user. If the path is to be treated as a Buffer, the implementation uses Buffer.from to obtain a Buffer from the result of path.resolve. By monkey-patching Buffer internals, namely...
