Description

Description

While doing some fuzzing using https://github.com/Endava/cats I discovered an issue for the /v1/user/keys" endpoint. Doing a POST with multipart/form-data; boundary=cats Content-Type results in a 500, rather that something more meaningful.

You can reproduce the issue using (just replace $token with your own token):

cats replay Test1246.json

Test1246.json.zip

Gitea Version

1.17.0+dev-573-ge45738e3c

Would it be possible to see some logs for this?

It could be reproduced by:

curl -v -XPOST -H "Authorization: token $token" -H "Content-Type: multipart/form-data; boundary=cats" "https://try.gitea.io/api/v1/user/keys"
