Description (last modified by Christopher Lenz)

I discovered a security in fine grain permission. When browsing a Changeset with changes not authorized to access, the html based of the diff output is dropped, but one thing missing….

The availability to download the diff in other formats:

Unified Diff

breaks the protection to gain access to the unauthorized information.

Are you saying that the unified diff actually contains the changes to files protected by authz? Looking at the code, I can't see how that is possible, but maybe I'm missing something.

Also, what version of Trac are you using? SVN trunk?

comment:3 by Richard Li, 19 years ago

Oh, yes, this is the case. I am using Trac 0.8 release and replaced the buggy authzperm.py with the newest one in the trunk.

Owner: changed from Jonas Borgström to Christopher Lenz
Status: new → assigned
Version: devel → 0.8

This problem has been fixed in trunk some time ago, so it only applies to the 0.8-stable branch.

Fixed in [1269]. You'll also need [1270] if you're using Python 2.1.

comment:6 by Richard Li, 19 years ago

Finally, I get the sources from 0.8-stable branch and merge the authzperm.py from [1184] back to replace the one in [967]. It is working alright in this way.

Will you update the authzperm.py in 0.8-stable to [1184] before releasing 0.8.1?

Done in [1274]. Thanks for the reminder.
