I've pushed a patch to clear secret-url access cookies on logout. I'm also changing this one from "Private security" to "Public security" because it is more a problem with the setup of the public computers, than with Mahara itself.
** Changed in: mahara Importance: Critical => Low ** Information type changed from Private Security to Public Security ** Summary changed: - Can illegially access pages that contain a secret url by normal url + Secret URLs used on public computers ** Summary changed: - Secret URLs used on public computers + Secret URLs used on public computers leak access to later users of the same browser session ** Summary changed: - Secret URLs used on public computers leak access to later users of the same browser session + Secret URLs used on public computers leak access to later users of the same browser -- You received this bug notification because you are a member of Mahara Contributors, which is subscribed to Mahara.

This can defy user expectations of access rights. Eg 1. group A admin creates a page and shares it only with the group, the page has the id=8 2. group A admin create a secret url for the page, eg /view/view.php?t=nFlSjpVuUCawH6TxP7A3 3. User 1, who is not in the group, goes to the page by its secret URL. (While using a computer at the library.) 4. User 1 then logs out, but doesn't close their browser window. 5. User 2 comes to the computer and goes to /view/view.php?id=8 Expected result - User 2 can't access the page as they don't know the secret url Actual result - User 2 can access the page This is reported here: https://mahara.org/interaction/forum/topic.php?id=6520 To manage notifications about this bug go to: https://bugs.launchpad.net/mahara/+bug/1385564/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~mahara-contributors Post to : [email protected] Unsubscribe : https://launchpad.net/~mahara-contributors More help : https://help.launchpad.net/ListHelp
