Overview

CVE-2020-15168 is a low-severity vulnerability. It was published on September 10, 2020 and has a CVSS 3.1 base score of 2.6 (LOW).

This vulnerability has a CVSS 3.1 base score of 2.6, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

node-fetch before versions 2.6.1 and 3.0.0-beta.9 did not honor the size option after following a redirect, which means that when a content size was over the limit, a FetchError would never get thrown and the process would end without failure. For most people, this fix will have a little or no impact. However, if you are relying on node-fetch to gate files above a size, the impact could be significant, for example: If you don't double-check the size of the data after fetch() has completed, your JS thread could get tied up doing work on a large file (DoS) and/or cost you money in computing.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
