My blog can't anonymous access,so i don't allow anybody visit my blog who not login in.i found a problem ,that when i visit http://my blog url/syndication.axd will see my posts.

I hope developer can fix it as soon as possible

Thanks ... you're right.  When turning off access to View Published Posts, they can still be seen thru the RSS feed.  This needs to be fixed.

Ben is this fix implemented in 2.5x? this issue still seems to happen on anonymous view of syndication.axd

The fix is in place:


public void ProcessRequest(HttpContext context)
    if (!Security.IsAuthorizedTo(Rights.ViewPublicPosts))
        context.Response.StatusCode = 401;

It's in the HttpHandlers/SyndicationHandler.cs.

Do you have "view public posts" revoked from anonymous users?

the only thing rights i have given "Anonymous" is "View Ratings on Posts" basically nothing.

When i go to my site anonymously, it prompts me to login (as expected)

but if i go to /syndication.axd i can browse the feed anonymously.

I'm using 2.5x

What could be wrong?

Just checked it on my family's blog, which is set as private. Works as expected - trying to load syndication.axd kicks me out to logon screen. Plain 2.5 out of the box... Not sure what you doing different.

is there a particular file or dll that i can replace again to make sure the change is reflected? I've gone through so many upgrades that perhaps the necessary files didn't copy over or get replaced...

The RSS feed is heavily cached.  Probably you are viewing a cached copy of the RSS feed that you initially viewed while you were logged in.  While logged out, go to syndication.axd and do a no-cache refresh (typically Ctrl-F5).   That should then attempt to retrieve the latest version from the server, and at that point, it should detect that you are anonymous and redirect you to the login page.
