Is S3BucketList safe?

Clean risk

S3BucketList monitors response headers across websites to identify S3 buckets and store their initiators locally.

S3BucketList watches browser response headers on all sites for Amazon S3 markers, then probes matching bucket URLs and ACL endpoints. It stores bucket hostnames, public status, owner and permission details, and the page that initiated the bucket response in local browser storage for display and export.
