CVE-2020-15168: Node-Fetch Project Node-Fetch

Medium severity, CVSS 5.3. EPSS: 1.7% chance of exploitation in the next 30 days.

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.

Affected products

• Node-Fetch Project Node-Fetch: before 2.6.1 (fixed in 2.6.1); version 3.0.0 only
