In my backend I create a signed url that the client uses for uploading directly to the storage.
I setup content-type and content-length by validating the request, but such parameters are then ignored when proceeding with the upload to the storage. I tried generating the url with one file then switching file and the upload still works fine.
I am worried of security issues with someone using a signed url to upload thousands of files or very large files. How likely is this to happen?
Thanks for your help!

Heya, @50e0782ec2a94d689f2ac4589feb74
Pre-signed URLs only offer temporary access for unauthorized users and eventually expire.
When generating a pre-signed URL, you can set the following parameters:
- Bucket – bucket containing or will be containing the object
- Key – object’s name
- Expires – amount of time the URL is valid
You can ensure that the signed URLs have a limited expiration time. By setting a short expiration time, you reduce the window of opportunity for malicious activities.
Hope that this helps!
