This PR addresses a Critical SSRF vulnerability in WebsiteAnalysisService. Previously, axios was configured to follow redirects automatically, which allowed an attacker to bypass the initial URL validation by redirecting to a private IP (Time-of-Check to Time-of-Use).

The fix implements manual redirect handling, ensuring that validateWebUrl is called for every URL in the redirect chain before fetching.

Verification:

  • New test backend/tests/websiteAnalysisService.security.test.ts confirms that redirects to private IPs are blocked.
  • Existing tests backend/tests/website-integration.test.ts confirm no regression in normal functionality.

…edirects

- Disable automatic redirects in axios (`maxRedirects: 0`)
- Implement manual redirect handling loop
- Validate every URL in the redirect chain using `validateWebUrl`
- Add security test `backend/tests/websiteAnalysisService.security.test.ts` to verify the fix
