Crown Jewel Targets

SSRF is highest-value when the target runs on cloud infrastructure (AWS, GCP, Azure) where metadata services expose credentials, or when the server sits inside a complex internal network (Kubernetes clusters, microservice meshes, internal APIs). Priority targets:

• Cloud-hosted SaaS products (GCP metadata at 169.254.169.254 or metadata.google.internal, AWS IMDSv1)
• Kubernetes/orchestration platforms — aggregated API servers, metrics-server, kubelet endpoints expose privileged cluster operations
• Internal developer tooling — CI/CD, workflow orchestration (Flyte, Argo), admin panels not exposed externally
• Link preview / URL fetching features — Reddit-style preview APIs, Slack-style unfurling, media processors
• Dataset/file import pipelines — anything that fetches remote URLs on behalf of a user
• Enterprise self-hosted software (GitHub Enterprise, GitLab) — SSRF frequently chains to RCE via internal services

Payouts are highest when SSRF reaches: cloud credentials → account takeover, internal admin APIs → data exfil, or chains to RCE.

Claims of blind SSRF require an out-of-band (OOB) confirmation. Always. No exceptions.
