XWiki Platform is a generic wiki platform. Starting in version 3.2-m3, users can deduce the content of the password fields by repeated call to `LiveTableResults` and `WikisLiveTableResultsMacros`. The issue can be fixed by upgrading to versions 14.7-rc-1, 13.4.4, or 13.10.9 and higher, or in version >= 3.2M3 by applying the patch manually on `LiveTableResults` and `WikisLiveTableResultsMacros`.

XWiki Platform is a generic wiki platform. Starting in version 6.0, users with write rights can insert well-formed content that is not handled well by the parser. As a consequence, some pages becomes unusable, including the user index (if the page containing the faulty content is a user page) and the page index.
Note that on the page, the normal UI is completely missing and it is not possible to open the editor directly to revert the change as the stack overflow is already triggered while getting the title of the document. This means that it is quite difficult to remove this content once inserted.
This has been patched in XWiki 13.10.10, 14.4.6, and 14.9-rc-1. A temporary workaround to avoid Stack Overflow errors is to increase the memory allocated to the stack by using the `-Xss` JVM parameter (e.g., `-Xss32m`). This should allow the parser to pass and to fix the faulty content. The consequences for other aspects of the system (e.g., performance) are unknown, and this workaround should be only be used as a temporary solution. The workaround does not prevent the issue occurring again with other content. Consequently, it is strongly advised to upgrade to a version where the issue has been patched.

This has been patched in the supported versions 13.10.10, 14.9-rc-1, and 14.4.6. As a workaround, it is possible to edit `FlamingoThemesCode.WebHomeSheet` and manually perform the changes from the patch fixing the issue.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. It's possible to make XWiki create many new schemas and fill them with tables just by using a crafted user identifier in the login form. This may lead to degraded database performance. The problem has been patched in XWiki 13.10.8, 14.6RC1 and 14.4.2. Users are advised to upgrade. There are no known workarounds for this issue.

xwiki-platform-icon-ui is vulnerable to Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection'). Any user with view rights on commonly accessible documents including the icon picker macro can execute arbitrary Groovy, Python or Velocity code in XWiki due to improper neutralization of the macro parameters of the icon picker macro. The problem has been patched in XWiki 13.10.7, 14.5 and 14.4.2. Workarounds: The [patch](https://github.com/xwiki/xwiki-platform/commit/47eb8a5fba550f477944eb6da8ca91b87eaf1d01) can be manually applied by editing `IconThemesCode.IconPickerMacro` in the object editor. The whole document can also be replaced by the current version by importing the document from the XAR archive of a fixed version as the only changes to the document have been security fixes and small formatting changes.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user with view rights on commonly accessible documents including the menu macro can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation due to improper escaping of the macro content and parameters of the menu macro. The problem has been patched in XWiki 14.6RC1, 13.10.8 and 14.4.3. The patch (commit `2fc20891`) for the document `Menu.MenuMacro` can be manually applied or a XAR archive of a patched version can be imported. The menu macro was basically unchanged since XWiki 11.6 so on XWiki 11.6 or later the patch for version of 13.10.8 (commit `59ccca24a`) can most likely be applied, on XWiki version 14.0 and later the versions in XWiki 14.6 and 14.4.3 should be appropriate.

XWiki Platform is vulnerable to Cross-Site Request Forgery (CSRF) that may allow attackers to delete or rename tags without needing any confirmation. The problem has been patched in XWiki 13.10.7, 14.4.1 and 14.5RC1. Workarounds: It's possible to patch existing instances directly by editing the page Main.Tags and add this kind of check, in the code for renaming and for deleting: ``` #if (!$services.csrf.isTokenValid($request.get('form_token'))) #set ($discard = $response.sendError(401, "Wrong CSRF token")) #end ```
