GeoNode vulnerable to SSRF Bypass to return internal host data

A SSRF vulnerability exists, bypassing existing controls on the software. This can allow a user to request internal services for a full read SSRF, returning any data from the internal network.

the application is using a whitelist, but the whitelist can be bypassed with @ and encoded value of @ (%40) GET /proxy/?url= This will trick the application that the first host is a whitelisted address, but the browser will use @ or %40 as a credential to the host geoserver on port 8080, this will return the data to that host on the response.
