What is CVE-2021-21650?

This oversight allows users with Item/Read permissions to access and retrieve sensitive information regarding artifacts uploaded to Amazon S3, provided the optional Run/Artifacts permission is enabled. As a result, unauthorized individuals may exploit this vulnerability to gain insight into the artifacts, potentially leading to exposure of confidential or sensitive data.
