CWE
  • CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')
Summary
A flaw was found in oauth-proxy. The application fails to properly validate the destination redirect parameter (`rd`) during post-login redirection.

This open redirect can be leveraged to conduct phishing attacks or credential theft.
