OWASP	A07:2021 - Identification and Authentication Failures
Confidence Level	Medium
Impact Level	High
Likelihood Level	High

Description

Granting public access to an S3 bucket using the grantPublicAccess method makes all objects in the bucket accessible to anyone on the internet. This bypasses authentication controls and exposes data to unauthorized users.

Impact

If exploited, attackers or anyone online could view, download, or misuse sensitive files stored in the bucket. This could lead to data leaks, regulatory violations, loss of intellectual property, or reputational damage to your organization.
