How it was found

hi team, here i found Open S3 Bucket Accessible by any User

vulnerable URL: https://cdn2.omise.co/

bucket name : omise-cdn-2

I haven't tried this yet as it may delete the bucket. (it is possible) an Attacker can delete the bucket using this command:- $ aws s3 rb s3://<The_bucket_name> and claim the bucket again to takeover the bucket

https://cdn2.omise.co/. (S3 misconfiguration), that allow to any user listing/read/download all folders/files.

i think somthing misconfiguration is happaening here, u cant read the bucket using Aws Cli but u can read it via browser. and also u can download the file using both Aws Cli and Browser.
