XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions it's possible to display or interact with any page a user cannot access through the combination of the async and display macros. A comment with either macro will be executed when viewed providing a code injection vector in the context of the running server. This vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8, and 13.10.11. Users are advised to upgrade. There are no known workarounds for this issue.

CVE-2023-29526 [CRITICAL] XWiki Platform's async and display macro allow displaying and interacting with any document in restricted mode
XWiki Platform's async and display macro allow displaying and interacting with any document in restricted mode
### 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
