Root for these RCs has been available under the guise of “FCC hack” for a really long time now; different groups have different exploits (it’s DJI so there are plenty) that work on different firmware versions.
Mostly they’re used to enable illegal RF parameters in Europe (FCC hack); DJI disabled strict geofencing in most of the “west” several years ago and that was also enforced in the drone anyway.
It doesn't have a web browser or, virtually, anything of use... but I think it supports enough of a web browser to log in into wifi captive portals.
