XWiki Platform is a generic wiki platform. Starting in version 13.10, it's possible to use the right of an existing document content author to execute a text area property. This has been patched in XWiki 14.10, 14.4.7, and 13.10.11. There are no known workarounds.
XWiki Platform is a generic wiki platform. Starting in version 2.3-milestone-1, the annotation displayer does not execute the content in a restricted context. This allows executing anything with the right of the author of any document by annotating the document. This has been patched in XWiki 13.10.11, 14.4.7 and 14.10. There is no easy workaround except to upgrade.
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 Commons are technical libraries common to several other top level XWiki projects. Starting in version 3.1-milestone-1, any user can edit their own profile and inject code, which is going to be executed with programming right. The same vulnerability can also be exploited in all other places where short text properties are displayed, e.g., in apps created using Apps Within Minutes that use a short text field. The problem has been patched on versions 13.10.9, 14.4.4, 14.7RC1.
XWiki Platform is a generic wiki platform. Starting in version 3.0-milestone-1, it's possible to execute a script with the right of another user, provided the target user does not have programming right. The problem has been patched in XWiki 14.8-rc-1, 14.4.5, and 13.10.10. There are no known workarounds for this issue.
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.
XWiki Platform is a generic wiki platform. Starting in version 12.10, a user without script rights can introduce a stored cross-site scripting by using the Live Data macro. This has been patched in XWiki 14.9, 14.4.7, and 13.10.10. There are no known workarounds.
XWiki Platform is a generic wiki platform. Starting in versions 6.3-rc-1 and 6.2.4, it's possible to inject arbitrary wiki syntax including Groovy, Python and Velocity script macros via the `newThemeName` request parameter (URL parameter), in combination with additional parameters. 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. Starting in version 14.3-rc-1, `org.xwiki.store.script.TemporaryAttachmentsScriptService#uploadTemporaryAttachment` returns an instance of `com.xpn.xwiki.doc.XWikiAttachment`. This class is not supported to be exposed to users without the `programing` right.
`com.xpn.xwiki.api.Attachment` should be used instead and takes case of checking the user's rights before performing dangerous operations. This has been patched in versions 14.9-rc-1 and 14.4.6. There are no known workarounds for this issue.
CKEditor Integration UI adds support for editing wiki pages using CKEditor. Prior to versions 1.64.3,t he `CKEditor.HTMLConverter` document lacked a protection against Cross-Site Request Forgery (CSRF), allowing to execute macros with the rights of the current user. If a privileged user with programming rights was tricked into executing a GET request to this document with certain parameters (e.g., via an image with a corresponding URL embedded in a comment or via a redirect), this would allow arbitrary remote code execution and the attacker could gain rights, access private information or impact the availability of the wiki. The issue has been patched in the CKEditor Integration version 1.64.3. This has also been patched in the version of the CKEditor integration that is bundled starting with XWiki 14.6 RC1. There are no known workarounds for this other than upgrading the CKEditor integration to a fixed version.
