## Security Tool Gap: Project Lacks Critical XXE Vulnerability Scanner for API Testing
A significant security testing gap has been identified in an open-source security tool: it currently lacks the ability to detect XML External Entity (XXE) injection vulnerabilities. This omission leaves a critical blind spot, particularly for API-focused security assessments where XML payloads are common in SOAP services, legacy APIs, and XML-RPC implementations. XXE is a recognized OWASP Top 10 threat (A05:2021 - Security Misconfiguration), capable of leading to sensitive file disclosure, server-side request forgery (SSRF), and denial-of-service attacks.

The proposed feature request calls for implementing a dedicated XXE scanner to test endpoints that accept XML input. The scanner would need to detect both in-band XXE, where file contents or errors are revealed in the response, and blind or out-of-band XXE, which would leverage the tool's existing callback server infrastructure to confirm exploitation. The project already possesses foundational components that could be adapted, including XML parsing logic in the crawler package and established scanner patterns for other vulnerabilities like SSRF and SSTI.

This missing capability represents a direct functional gap that could undermine the tool's effectiveness in modern application security testing. Without it, security professionals using the tool risk missing a high-severity vulnerability class in applications that process XML. The integration of such a scanner would align the tool more closely with industry-standard vulnerability coverage and enhance its utility for comprehensive API security audits.
