Since then, AWS introduced IMDSv2 (which requires a PUT token first). However, many legacy applications still use IMDSv1, or they misconfigure IMDSv2. curl-url-http-3A-2F-2F169.254.169.254-2Flatest-2Fapi-2Ftoken

This forces the PUT token method — but as shown, your keyword is exactly that method, so it doesn’t prevent the attack; it only prevents IMDSv1 fallback. This article will break down: The /latest/api/token endpoint

This article will break down:

The /latest/api/token endpoint is part of the AWS Instance Metadata Service. When you make a request to this endpoint, you are essentially asking for a token that can be used to access other metadata about the instance.

: IMDSv2 requires this token to protect against SSRF vulnerabilities that could leak sensitive instance data.
