S3BucketOrigin.withOriginAccessControl: No Option to add ListBucket permission

[andyfase]

Describe the bug

The withOriginAccessControl method only has functionality to add GetObject, PutObject or DeleteObject permissions to the provided bucket resource policy. When using CloudFront to host a SPA app (Single Page App) its common to require to put a custom error response to translate HTTP 404 (page not found) to HTTP 200 responses, this is support deep linking within the SPA app.

To allow for this the S3 bucket must provide ListBucket permission to CloudFront, allowing CloudFront to identify the file doesnt exist and actually omit a HTTP 404. Currently this is not exposed via withOriginAccessControl and a user has no understand this and then add the permission manally to the bucket policy

Given the code for withOriginAccessControl is already modifiing the bucket resource policy it should be expected that it also handles this use case

Expected Behavior

Bucket Policy has the ability to have ListBucket permissions granted to CloudFront

Current Behavior

Only GetObject permissions added to the /* resource ARN - ListBucket needs to be to the bucket resource not a Key resource

Reproduction Steps

use withOriginAccessControl and see that ListBucket permission cannot be added

Possible Solution

Expose functionality (extra prop) to withOriginAccessControl to allow for ListBucket permission adding

### This permission allows CloudFront to handle 404 errors and deliver custom error responses, which is essential for deep linking within the SPA.

public withOriginAccessControl(props?: { allowListBucket?: boolean }) { const bucketPolicy = { // already have permissions GetObject: true, PutObject: true, DeleteObject: true, };

if (props?.allowListBucket) { // Add ListBucket permission to the bucket resource policy bucketPolicy.ListBucket = true; }

this.updateBucketPolicy(bucketPolicy); } Once this adjustment is made, users will able to add the ListBucket permission directly through with OriginAccessControl, simplifying the process and avoiding need for manual modifications to the bucket policy.

@andyfase , thanks for reaching out.

Looks like this past issue is similar to the one you have created- https://github.com/aws/aws-cdk/issues/13983 . Could you please take a look and confirm the same?

Thanks.

Hi @khushail

Yes that past issue is similar - but that is to for OAI access pattern vs the newer OAC.

I agree with the comments made in that issue that adding ListBucket should be "opt-in" to prevent the exposure of the contents of the bucket if a index.html isnt present (i.e. the developer should have to enable this).
