Purpose and scope of an API security scanner
An API security scanner performs automated, read-only assessment of HTTP interfaces without requiring code changes or agents. It submits requests, observes responses, and derives a risk score with prioritized findings. Because it operates externally, it complements internal testing rather than replacing deep code review or architecture design.
Detection coverage aligned to industry standards
The scanner maps findings to three frameworks: PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). It covers 12 security categories including authentication bypass, JWT misconfigurations such as alg=none or expired tokens, BOLA and IDOR via sequential ID probing, BFLA and privilege escalation indicators, property over-exposure, input validation issues like CORS wildcard usage, rate-limiting anomalies, data exposure patterns including PII and API key formats, encryption misconfigurations, SSRF indicators, inventory management deficiencies, and unsafe consumption surfaces. For LLM-facing endpoints, it runs 18 adversarial probes across Quick, Standard, and Deep tiers, targeting system prompt extraction, jailbreak techniques, data exfiltration attempts, and token smuggling.
OpenAPI spec analysis and authenticated scanning
The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 documents with recursive $ref resolution, cross-referencing spec definitions against runtime behavior to identify undefined security schemes, sensitive field exposure, deprecated operations, and missing pagination. Authenticated scanning supports Bearer, API key, Basic auth, and Cookie methods. Domain verification is enforced through DNS TXT records or HTTP well-known files so only domain owners can submit credentials. A strict header allowlist ensures only Authorization, X-API-Key, Cookie, and X-Custom-* headers are forwarded during tests.
Deployment options and continuous monitoring
Results are accessed through a web dashboard that provides scan history, score trends, and downloadable compliance PDFs. The CLI supports commands such as middlebrick scan <url> with JSON or text output. A GitHub Action can gate CI/CD pipelines, failing builds when scores drop below configured thresholds. The MCP Server enables scanning from AI coding assistants. For ongoing risk tracking, Pro tier offers scheduled rescans every 6 hours, daily, weekly, or monthly, with diff detection for new and resolved findings. Email alerts are rate-limited to one per hour per API, and webhooks use HMAC-SHA256 signatures with auto-disable after five consecutive failures.
Limitations and responsible usage
The scanner does not fix, patch, or block issues; it reports findings with remediation guidance. It does not execute active SQL injection or command injection payloads, as those tests fall outside its read-only design. Business logic vulnerabilities require human expertise tied to your domain context. Blind SSRF is out of scope due to the absence of out-of-band infrastructure, and the tool cannot replace a human pentester for high-stakes audits. These constraints ensure clear boundaries between detection and remediation.
