| node-fetch | = 3.0.0< 2.6.1 | 2.6.1 |

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.
We released patched versions for both stable and beta channels:
v2: 2.6.1v3: 3.0.0-beta.9None, it is strongly recommended to update as soon as possible.
