API Security Testing
— SSRF Code Review
Manual validation and exploit-focused API Security Testing. We help SSRF Code Review-based companies proactively secure their digital assets before attackers strike.
Free Scoping CallSSRF Code Review delivery and security model
Source-code review for user-controlled outbound request risk in webhooks, URL imports, file fetchers, avatar proxies, and integration callbacks.
Focus areas
- User-controlled URL and fetch points
- Allowlist, DNS pinning, and redirect controls
- Cloud metadata and internal network access risk
- Webhook and integration callback flows
Delivery notes
- Risky outbound request paths are tied to target surfaces
- Internal network or metadata impact is explained safely
- Remediation maps to allowlists and egress policy
Decision matrix
SSRF Code Review is not just a service label; it states how each control is validated and which evidence is expected at closure.
| Control | Decision question | Validation | Expected evidence |
|---|---|---|---|
| User-controlled URL and fetch points | Does User-controlled URL and fetch points create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in API Security Testing. | Risky outbound request paths are tied to target surfaces |
| Allowlist, DNS pinning, and redirect controls | Does Allowlist, DNS pinning, and redirect controls create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in API Security Testing. | Internal network or metadata impact is explained safely |
| Cloud metadata and internal network access risk | Does Cloud metadata and internal network access risk create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in API Security Testing. | Remediation maps to allowlists and egress policy |
| Webhook and integration callback flows | Does Webhook and integration callback flows create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in API Security Testing. | Risky outbound request paths are tied to target surfaces |
What if User-controlled URL and fetch points fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.
What if Allowlist, DNS pinning, and redirect controls fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.
What if Cloud metadata and internal network access risk fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.

Frequently Asked Questions
What decision does SSRF Code Review clarify?
SSRF Code Review clarifies exploitability, affected workflows, and release impact for API Security Testing with evidence rather than scanner noise.
What evidence is included in SSRF Code Review?
Risky outbound request paths are tied to target surfaces Also, Internal network or metadata impact is explained safely. Retest criteria and ownership notes are included for closure.
How is this different from an automated scanner report?
Automated findings are not forwarded as-is; false positives are removed, abuse paths are proven, and remediation priority is explained.
