4th percentile - higher than 4% of all known CVEs

Summary

A file-upload handler redirects the authenticated client's browser to a URL taken directly from that same request's Referer header, without validating it against the application's own origin. This allows an authenticated attacker to craft a request that causes another user's browser to be redirected to an arbitrary external destination after completing an upload.

Risk Assessment

An attacker can exploit this vulnerability to redirect users to malicious sites, potentially leading to phishing or data theft. However, it requires interaction from an authenticated user.

Recommendation

Update the application to a version that validates the redirect URL against its own origin. Until then, consider restricting the file-upload functionality.
