Summary
XWiki Platform's async and display macro allow displaying and interacting with any document in restricted mode
Details

Impact

It's possible to display any page you cannot access through the combination of the async and display macro.

Steps to reproduce:

  1. Enable comments for guests by giving guests comment rights
  2. As a guest, create a comment with content {{async}}{{display reference="Menu.WebHome" /}}{{/async}}
  3. Open the comments viewer from the menu (appends ?viewer=comments to the URL)

-> the Menu.WebHome is displayed while the expectation would be to have an error that the current user is not allowed to see it

Patches

The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8, and 13.10.11.

Workarounds

There is no known workaround.
