Upgrade fsevents to version 1.2.11 or higher.
Amendment
This was deemed not a vulnerability.
Overview
Affected versions of this package are vulnerable to Exposure of Resource to Wrong Sphere by loading a binary from an insecure hardcoded S3 bucket URL, which was demonstrated by an ethical hacker to be susceptible to takeover by malicious actors and used to conduct remote code execution. Loading the remote binary was removed in version 1.2.11 meaning this and later versions were not exposed to this attack vector.
During the disclosure process Snyk confirmed with the security researcher that AWS had agreed to take ownership and block all access to the S3 bucket and as such it has mitigated the straightforward attack vector - this can be further confirmed by attempting to access the bucket which returns a AllAccessDisabled or NoSuchBucket error.
Further documentation about buckets-reuse can be found in AWS Documentation.
