CVE-2020-15168 Moderate

CVE-2020-15168

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.

### Impact Node Fetch 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. ### Patches We released patched versions for both stable and beta channels: - For `v2`: 2.6.1 - For `v3`: 3.0.0-beta.9 ### Workarounds None, it is strongly recommended to update as soon as possible. ### For more information If you have any questions or comments about this advisory: * Open an issue in [node-fetch](https://github.com/node-fetch/node-fetch/issues/new?assignees=&labels=question&template=support-or-usage.md&title=Question%3A+) * Contact one of the core maintainers.
