If you append an IAM role name (e.g., MyAppRole ), the complete request becomes:

Block requests pointing to internal IP ranges, including private subnets ( 10.0.0.0/8 , 172.16.0.0/12 , 192.168.0.0/16 ) and link-local space ( 169.254.169.254/32 ). 3. Implement Least Privilege IAM Roles

: 169.254.169.254 is a link-local address accessible only from within the instance.

If an application is compromised via SSRF, the damage is capped by the permissions of the EC2 instance's IAM role. Ensure that EC2 instances only have the absolute minimum permissions required to perform their tasks. Never attach administrative or overly broad permissions to an instance profile. 4. WAF Rules and Monitoring If an application is compromised via SSRF, the

The IP address 169.254.169.254 is a link-local address used by AWS to host the Instance Metadata Service. This service is accessible only from within the EC2 instance itself. It provides data about the instance, including its network configuration, instance ID, and, most importantly, temporary security credentials associated with the IAM role assigned to that instance. The Anatomy of the Attack

If userUrl is http://169.254.169.254/latest/meta-data/iam/security-credentials/MyRole , the server will fetch and leak the credentials.

As cloud architects and developers, we must:

The attacker forces the application to request the metadata endpoint.
