Find OWASP API Top 10 vulnerabilities before attackers do. Run VulnAPI in CI/CD and get actionable fixes — not just alerts.
Built for security-minded teams.
Catch vulnerabilities before your users — or your auditors — do.
Comprehensive Scanning
Detects vulnerabilities from Broken Authentication to Security Misconfiguration, covering the OWASP API Top 10.
Easy CI/CD Integration
Seamlessly fits into your existing pipelines for continuous, automated security checks.
Open Source
Community-driven project released under the MIT License.
Actionable Insights
Detailed reports with clear remediation recommendations so you know exactly what to fix.
Continuously Updated
The community keeps threat detection capabilities current with emerging vulnerabilities.
Customizable Scanning
Tailor security assessments to your specific requirements and environments.
Security that keeps up with your code.
VulnAPI integrates directly into the way you already build — scanning your APIs automatically, surfacing real vulnerabilities, and telling you exactly how to fix them.
🔍
Scan your APIs and see every vulnerability in seconds.
Point VulnAPI at any REST or GraphQL endpoint and get a complete picture of your attack surface. Each finding is mapped directly to an OWASP API Top 10 category with a severity rating — so you know what’s critical and what can wait.
Broken Authentication
POST /auth/token
Broken Object Property Level Auth
GET /users/{id}
Server Side Request Forgery
POST /webhooks
Security Misconfiguration
GET /health
⚡
Block vulnerable code before it merges.
Drop VulnAPI into any CI/CD pipeline with a single step. Set severity thresholds to automatically fail builds when critical vulnerabilities are detected — so insecure APIs never reach staging or production. Works with GitHub Actions, GitLab CI, Jenkins, and more.
📋
Not just alerts — a clear path to the fix.
Every finding includes a plain-English description of the vulnerability, the exact request that triggered it, and concrete remediation steps your team can act on immediately. No guesswork, no Googling OWASP docs at 2am.
Broken Authentication
API2:2023 · POST /auth/token
Description
The token endpoint does not enforce rate limiting or account lockout. An attacker can perform unlimited credential stuffing or brute-force attacks without triggering any block.
Triggered by
POST /auth/token HTTP/1.1
Content-Type: application/json
{"username":"admin","password":"..."}
# 200 OK after 1000 attempts
Remediation
- →Implement rate limiting (e.g. 5 attempts / 15 min per IP)
- →Add exponential backoff after failed attempts
- →Return 429 Too Many Requests on threshold breach
