The HTTP client module superagent is vulnerable to ZIP bomb attacks. In a ZIP bomb attack, the HTTP server replies with a compressed response that becomes several magnitudes larger once uncompressed. If a client does not take special care when processing such responses, it may result in excessive CPU and/or memory consumption. An attacker might exploit such a weakness for a DoS attack. To exploit this the attacker must control the location (URL) that superagent makes a request to.

Affected: npm: superagent

Affected versions of `superagent` do not check the post-decompression size of ZIP compressed HTTP responses prior to decompressing. This results in the package being vulnerable to a [ZIP bomb](https://en.wikipedia.org/wiki/Zip_bomb) attack, where an extremely small ZIP file becomes many orders of magnitude larger when decompressed.

This may result in unrestrained CPU/Memory/Disk consumption, causing a denial of service condition.

## Recommendation

Update to version 3.7.0 or later.

Affected: Ubuntu:16.04:LTS: node-superagent, Ubuntu:18.04:LTS: node-superagent
