fsevents is vulnerable to Remote Code Execution. The vulnerability is caused by loading a fsevents binary from an arbitrary AWS S3 bucket during installation. This S3 bucket URL was vulnerable to take over by malicious actors, but a security researcher claimed the bucket URL to protect against attackers. AWS has since blacklisted the bucket URL, to prevent further attacks.
