XWiki Platform is a generic wiki platform. Starting in version 5.0-rc-1 and prior to versions 14.10.19, 15.5.4, and 15.9-rc-1, it is possible to access the hash of a password by using the diff feature of the history whenever the object storing the password is deleted. Using that vulnerability it's possible for an attacker to have access to the hash password of a user if they have rights to edit the users' page. With the default right scheme in XWiki this vulnerability is normally prevented on user profiles, except by users with Admin rights. Note that this vulnerability also impacts any extensions that might use passwords stored in xobjects: for those usecases it depends on the right of those pages. There is currently no way to be 100% sure that this vulnerability has been exploited, as an attacker with enough privilege could have deleted the revision where the xobject was deleted after rolling-back the deletion. But again, this operation requires high privileges on the target page (Admin right). A page with a user password xobject which have in its history a revision where the object has been deleted should be considered at risk and the password should be changed there. a diff, to ensure it's not coming from a password field. As another mitigation, admins should ensure that the user pages are properly protected: the edit right shouldn't be allowed for other users than Admin and owner of the profile (which is the default right). There is not much workaround possible for a privileged user other than upgrading XWiki.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The rollback action is missing a right protection, a user can rollback to a previous version of the page to gain rights they don't have anymore. The problem has been patched in XWiki 14.10.17, 15.5.3 and 15.8-rc-1 by ensuring that the rights are checked before performing the rollback.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. XWiki is vulnerable to a remote code execution (RCE) attack through its user registration feature. This issue allows an attacker to execute arbitrary code by crafting malicious payloads in the "first name" or "last name" fields during user registration. This impacts all installations that have user registration enabled for guests. This vulnerability has been patched in XWiki 14.10.17, 15.5.3 and 15.8 RC1.

XWiki Platform is a generic wiki platform. Starting in 2.3 and prior to versions 14.10.15, 15.5.2, and 15.7-rc-1, anyone who can edit an arbitrary wiki page in an XWiki installation can gain programming right through several cases of missing escaping in the code for displaying sections in the administration interface. This impacts the confidentiality, integrity and availability of the whole XWiki installation. Normally, all users are allowed to edit their own user profile so this should be exploitable by all users of the XWiki instance. This has been fixed in XWiki 14.10.15, 15.5.2 and 15.7RC1. The patches can be manually applied to the `XWiki.ConfigurableClassMacros` and `XWiki.ConfigurableClass` pages.

XWiki Platform is a generic wiki platform. Starting in 7.2-milestone-2 and prior to versions 14.10.15, 15.5.2, and 15.7-rc-1, the Solr-based search in XWiki discloses the password hashes of all users to anyone with view right on the respective user profiles. By default, all user profiles are public. This vulnerability also affects any configurations used by extensions that contain passwords like API keys that are viewable for the attacker. Normally, such passwords aren't accessible but this vulnerability would disclose them as plain text. This has been patched in XWiki 14.10.15, 15.5.2 and 15.7RC1. There are no known workarounds for this vulnerability.

XWiki Platform is a generic wiki platform. Prior to versions 14.10.15, 15.5.2, and 15.7-rc-1, the Solr-based search in XWiki discloses the email addresses of users even when obfuscation of email addresses is enabled. To demonstrate the vulnerability, search for `objcontent:email*` using XWiki's regular search interface. This has been fixed in XWiki 14.10.15, 15.5.2 and 15.7RC1 by not indexing email address properties when obfuscation is enabled. There are no known workarounds for this vulnerability.

XWiki Platform is a generic wiki platform. Starting in 4.5-rc-1 and prior to versions 14.10.15, 15.5.2, and 15.7-rc-1, the search administration interface doesn't properly escape the id and label of search user interface extensions, allowing the injection of XWiki syntax containing script macros including Groovy macros that allow remote code execution, impacting the confidentiality, integrity and availability of the whole XWiki instance. This attack can be executed by any user who can edit some wiki page like the user's profile (editable by default) as user interface extensions that will be displayed in the search administration can be added on any document by any user. The necessary escaping has been added in XWiki 14.10.15, 15.5.2 and 15.7RC1. As a workaround, the patch can be applied manually applied to the page `XWiki.SearchAdmin`.

XWiki Platform is a generic wiki platform. Starting in 2.3 and prior to versions 14.10.15, 15.5.2, and 15.7-rc-1, there is a reflected XSS or also direct remote code execution vulnerability in the code for displaying configurable admin sections. The code that can be passed through a URL parameter is only executed when the user who is visiting the crafted URL has edit right on at least one configuration section. While any user of the wiki could easily create such a section, this vulnerability doesn't require the attacker to have an account or any access on the wiki. It is sufficient to trick any admin user of the XWiki installation to visit the crafted URL. This vulnerability allows full remote code execution with programming rights and thus impacts the confidentiality, integrity and availability of the whole XWiki installation. This has been fixed in XWiki 14.10.15, 15.5.2 and 15.7RC1. The patch can be manually applied to the document `XWiki.ConfigurableClass`.

XWiki Platform is a generic wiki platform. Starting in version 6.3-milestone-2 and prior to versions 14.10.15, 15.5.1, and 15.6RC1, the Solr-based search suggestion provider that also duplicates as generic JavaScript API for search results in XWiki exposes the content of all documents of all wikis to anybody who has access to it, by default it is public. This exposes all information stored in the wiki (but not some protected information like password hashes). While there is a right check normally, the right check can be circumvented by explicitly requesting fields from Solr that don't include the data for the right check. This has been fixed in XWiki 15.6RC1, 15.5.1 and 14.10.15 by not listing documents whose rights cannot be checked. No known workarounds are available.
