I am using the Filestack JS Picker and have a private s3 bucket ("Block all public access" is enabled) to which I want to upload files directly from the frontend via the Picker widget. However I am getting a 403 (Forbidden) error.
In the documentation I see an option to upload to a private s3 location access: private https://www.filestack.com/docs/api/file/#store-qp
However i don't see much guidance/documentation on how exactly to allow an upload to that private bucket from my Picker. Is this even possible (to keep the bucket private but allow the upload from my website via the Picker) ? And is it something that I should be configuring on the filestack portal or do I somehow need to give my bucket a new policy.
As far as I can tell, the upload first goes to filestackapi.com and presumably it then gets redirected to my bucket.
Thanks

Using the cloudfront to read and write in the same S3 bucket, how can I prohibit a user from using a read-presigned url to make an injection (upluad)?
Thanks.
Deny access to PUT for cloudfront and it won't be able to put data into s3. In s3 permissions you can allow read only calls from cloudfront only. Turn off public access on s3, to make sure it will allow gets only from cloudfront. On CloudFront use this to update s3 bucket access, before this disable any public access on s3. CF will update S3's policy & create CF origin access identity:
To put data into S3, use presigned URL and it all goes down to the place where you create the presigned URL for upload. You may have api gateway RESTfull tiny api which would authenticate user to get the upload url and would return the upload url, which would be used by user to upload data to S3.
I'm using custom domain and CloudFront for S3 static hosting site to serve https.
It's working fine when I open the pages through the app's internal buttons or link,
but if I input direct URL in the address bar, or click the browser refresh button, it shows
This XML file does not appear to have any style information associated with it. The document tree is shown below.... Access Denied error screen.
I searched related answers and tried to /index.html in the CloudFront general setting as Default Root Object but it didn't work. (Before this try, it was index.html)
When I updated it as /index.html, even the domain itself didn't work.
I have another S3 static hosting site without CloudFront and certificate just for testing.
This site is working fine even I input direct url or click the refresh button.
Above two S3 bucket have same settings (root object is index.html and error document is also index.html)
After this, I changed CloudFront Origin Domain Name from REST endpoint to website endpoint referred to this docs (https://aws.amazon.com/premiumsupport/knowledge-center/s3-website-cloudfront-error-403/)
But now getting this error when I refresh the screen.
All the object in S3 is owned to bucket owner and has public access.
This app is made by React and using react-router-dom.
Could you give me any hint or advice?
Thanks.
Solved...
My S3 bucket region requires . instead of - when I use website endpoint for cloudfront.
And FYI..
In my case, there are some little difference with the document and some tutorial. My CloudFront distribution doesn't need to use default root object, and individual objects in S3 has no public access but the bucket has it.
There are some specific endpoints to be used for website hosting buckets, which are listed in the Amazon Simple Storage Service endpoints and quotas document. For example, when hosting in eu-west-1, cloudfront will prepopulate the dropdown with example.s3.eu-west-1.amazonaws.com, but if you look into the bucket settings, Static website hosting section, it will show you the correct url example.s3-website-eu-west-1.amazonaws.com
Carefully read the table! The url scheme is not fully consistent, eg. s3-website.us-east-2.amazonaws.com but s3-website-us-east-1.amazonaws.com - just to make your day a bit more joyful.
So I had the exact same issue and was able to resolve it after taking the s3 bucket endpoint located in the properties of the s3 bucket and then pasting it into the cloudfront origins section into the origin domain. I removed the beginning of the endpoint for example: "http://website.com.s3-website.us-east-2.amazonaws.com" you would just remove the "http://" and then post the rest into the cloudfront origin domain and click save. That should solve the problem!
I tried all kinds of different options such as making sure every object was public as well in the s3 bucket. Make sure your s3 bucket is also publicly available.
Certain regions do have different endpoints for your s3 buckets. Here is a link that shows more of that: https://aws.amazon.com/premiumsupport/knowledge-center/s3-rest-api-cloudfront-error-403/
I've uploaded a file using the SDK to my private S3 bucket.
I can access this file through the S3 UI.
However, I cannot access this file through a direct link. It gives me some XML that includes "AccessDenied" as a code and message.
It seems reasonable that since I'm authenticated in the browser and am clicking on a direct link to the file from the same browser, that I should be allowed through. At the very least, I should be directed to a login page.
Does anyone have any experience with this?
So after working on this for a bit, I discovered the best thing is to simply publish the console URL to the file.
https://s3.console.aws.amazon.com/s3/object/{your bucket}/{your file path}?region={the region of your bucket}&tab=overview
Be mindful to specify the correct region. If you're forming this programmatically, then use Amazon.RegionEndpoint.SystemName.
If you're not logged in, it will ask you for your login!
No signed URL is necessary.
Thanks to everyone who contributed!
There are 2 places that you need to make sure are set correctly based on how you want to setup access to the bucket. It will either have public or private access.
The properties tab:
Here you can set what you will use the bucket for.
The Permissions tab -> Bucket Policy:
With this, you can then setup access. I was able to generate a policy with this site:
http://awspolicygen.s3.amazonaws.com/policygen.html
EDIT:
Mine is working with the settings I have shown. I recommend asking the AWS boards if to get to the bottom of it. You could also try this:
You can use the direct link if you are inside a VPC. You have to :
1- Create a VPC endpoint for Amazon S3.
2- Add a bucket policy that allows access from the VPC endpoint.
All steps are described in the following link :
https://aws.amazon.com/premiumsupport/knowledge-center/s3-private-connection-no-authentication/?nc1=h_ls
The scenario:
Amazon S3 folder with private files
Goal: display videos on a HTML5 player, on a specific domain, without turning these files public (similar to vimeo allowing to embed a video only on a domain)
I already tried to change the bucket policy but without success!
You'll want to set these files to private.
You'll want to use pre-signed URLs to get the correct authentication token that is required for you to view the files after they're set to private.
If your player is web-based, you'll probably want to enable a CORS configuration.
I have been playing around a little with amazon s3 as a storage backend and I noticed that you can now serve static websites on s3.
I tried uploading a simple site and it worked well, but I thought it would be great if you could set the files to private and generate a signed url to view the site.
Unfortunately, it seems that generating a signed url for the index page allows you to view that page, but predictably enough all the images are missing as they are set to private and so require there own signed url.
As I am new to s3 and amazon services I wondered if anyone else had managed a private site from s3 and or using s3 with a combination of other amazon services(cloudfront etc)
I tried to find out how to do the same thing to keep the site private during development. I think this is not possible with S3. Someone has the same question in the AWS forum: https://forums.aws.amazon.com/thread.jspa?threadID=81688
Bottom line: "I'm afraid you will need to host the website outside of S3 until you are ready to go public."
