An authentication bypass vulnerability exists libcurl <8.0.0 in the connection reuse feature which can reuse previously established connections with incorrect user permissions due to a failure to check for changes in the CURLOPT_GSSAPI_DELEGATION option.

The safest option is to not reuse connections if the CURLOPT_GSSAPI_DELEGATION option has been changed.
