Ok, I think I found a way to do it.
First get the proxy of the filter itself

<http://public.kitware.com/pipermail/paraview/2011-November/023336.html>):
import paraview.servermanager as sm
proxies = sm.ProxyManager().GetProxiesInGroup("sources").values()
selfProxy = [p for p in proxies if p.GetClientSideObject() is self][0]
Then get the selected points of the proxy’s input like this
(http://stackoverflow.com/a/27805049):
proxy = paraview.simple.GetActiveSource()
active_selection = proxy.GetSelectionInput(proxy.Port)
