CVE-2026-59874 · node-tar: Negative tar entry size causes infinite loop in archive replace

This page contains facts from public vulnerability sources. Check the original advisory before updating.

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.18, tar.replace accepts a checksum-valid tar header with a negative base-256 encoded entry size, causing the archive scanner to make no progress while repeatedly parsing the same header. This issue is fixed in version 7.5.18.
