What CGPulse checks
A resource passes this rule when metadataOptions.httpTokens must equal required. Anything else is reported as a finding with the evaluated property value attached as evidence.
How to fix it
Require IMDSv2 to prevent SSRF-based credential theft from the metadata service. In AWS Console: EC2 > Instance settings > Modify instance metadata options > set HttpTokens to required. See: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html
