I'm using the List Category Posts plugin, and it isn't listing posts marked private, even if the appropriate user is logged in. Is there a fix for this?
List Category Posts plugin uses get_posts to actually get the posts and its default post_status is publish and that is way you won't get any private posts.
To "Fix" it you can edit the file named include/CatList.php of the plugin and add
before line 51 before
this will get you only private posts and to really "FIX" it you need to add this code:
on line 51 again before
and offer the author of the plugin this as a patch so the next time he updates you want lose this fix.
