CVE-2026-77301

adm-zip is a JavaScript library for creating and extracting ZIP archives in Node.js. Prior to 0.6.1, getData in zipEntry.js trusts an entry's central-directory uncompressed size and allocates output memory before validating that value against the actual compressed data and decompression result. A...

CVE-2026-39244: Uncontrolled Resource Consumption

adm-zip before 0.5.18 is vulnerable to denial of service via a crafted ZIP file with a manipulated uncompressed size header field. In zipEntry.js line 103, Buffer.alloccentralHeader.size allocates memory based on the declared uncompressed size from the ZIP central directory header without...

CVE-2026-44004: Allocation of Resources Without Limits or Throttling

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, sandboxed code can call Buffer.alloc with an arbitrary size to allocate memory directly on the host heap. Because Buffer.alloc is a synchronous C++ native call, vm2's timeout option cannot interrupt it. A single request can exhaust ho...

CVE-2025-55131: Buffer Copy without Checking Size of Input

A flaw in Node.js's buffer allocation logic can expose uninitialized memory when allocations are interrupted, when using the vm module with the timeout option. Under specific timing conditions, buffers allocated with Buffer.alloc and other TypedArray instances like Uint8Array may contain leftover...
