Overview
tar is a full-featured Tar for Node.js.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of enforced upper bounds on total decompressed data, entry counts, or decompression ratio in extraction and parsing paths such as src/extract.ts. An attacker can exhaust disk space and CPU resources by submitting a small crafted gzip archive with a high decompression ratio.
