Include private gallery2 rss feed

Hi,
I use WP+gallery (with wpg2 plugin). I want to show lastest gallery2 comments on login required albums in WP.
Before a security patch of G2, i was able to access these comments although they were on login required images. But now it’s forbidden : no more access to that feed without login into G2.
Any idea to import this rss in WP with that restriction ? I thougt about a way to use the fact that WPG2 logs the user in G2, but I didn’t succeed.
Thx
