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. 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.

The XWiki Admin Tools Application provides tools to help the administration of XWiki. Prior to version 4.5.1, a cross-site request forgery vulnerability in the query on XWiki tool allows executing arbitrary database queries on the database of the XWiki installation. Among other things, this allows modifying and deleting all data of the wiki. This could be both used to damage the wiki and to create an account with elevated privileges for the attacker, thus impacting the confidentiality, integrity and availability of the whole XWiki instance. A possible attack vector are comments on the wiki, by embedding an image with wiki syntax like `[[image:path:/xwiki/bin/view/Admin/QueryOnXWiki?query=DELETE%20FROM%20xwikidoc]]`, all documents would be deleted from the database when an admin user views this comment. This has been patched in Admin Tools Application 4.5.1 by adding form token checks. Some workarounds are available. The patch can also be applied manually to the affected pages. Alternatively, if the query tool is not needed, by deleting the document `Admin.SQLToolsGroovy`, all database query tools can be deactivated.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions it's possible for a user to execute any content with the right of an existing document's content author, provided the user have edit right on it. A crafted URL of the form ` /xwiki/bin/edit//?content=%7B%7Bgroovy%7D%7Dprintln%28%22Hello+from+Groovy%21%22%29%7B%7B%2Fgroovy%7D%7D&xpage=view` can be used to execute arbitrary groovy code on the server. This vulnerability has been patched in XWiki versions 14.10.6 and 15.2RC1. Users are advised to update. There are no known workarounds for this issue.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. XWiki doesn't properly escape the section URL parameter that is used in the code for displaying administration sections. This allows any user with read access to the document `XWiki.AdminSheet` (by default, everyone including unauthenticated users) to execute code including Groovy code. This impacts the confidentiality, integrity and availability of the whole XWiki instance. This vulnerability has been patched in XWiki 14.10.14, 15.6 RC1 and 15.5.1. Users are advised to upgrade. Users unablr to upgrade may apply the fix in commit `fec8e0e53f9` manually. Alternatively, to protect against attacks from unauthenticated users, view right for guests can be removed from this document (it is only needed for space and wiki admins).

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The create action is vulnerable to a CSRF attack, allowing script and thus remote code execution when targeting a user with script/programming right, thus compromising the confidentiality, integrity and availability of the whole XWiki installation. When a user with script right views this image and a log message `ERROR foo - Script executed!` appears in the log, the XWiki installation is vulnerable. This has been patched in XWiki 14.10.9 and 15.4RC1 by requiring a CSRF token for the actual page creation.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. XWiki supports scheduled jobs that contain Groovy scripts. Currently, the job checks the content author of the job for programming right. However, modifying or adding a job script to a document doesn't modify the content author. Together with a CSRF vulnerability in the job scheduler, this can be exploited for remote code execution by an attacker with edit right on the wiki. If the attack is successful, an error log entry with "Job content executed" will be produced. This vulnerability has been patched in XWiki 14.10.9 and 15.4RC1.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The REST API allows executing all actions via POST requests and accepts `text/plain`, `multipart/form-data` or `application/www-form-urlencoded` as content types which can be sent via regular HTML forms, thus allowing cross-site request forgery. With the interaction of a user with programming rights, this allows remote code execution through script macros and thus impacts the integrity, availability and confidentiality of the whole XWiki installation. For regular cookie-based authentication, the vulnerability is mitigated by SameSite cookie restrictions but as of March 2023, these are not enabled by default in Firefox and Safari. The vulnerability has been patched in XWiki 14.10.8 and 15.2 by requiring a CSRF token header for certain request types that are susceptible to CSRF attacks.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). For instance, the following URL execute an `alter` on the browser: `<xwiki-host>/xwiki/bin/view/Main/?viewer=share&send=1&target=&target=%3Cimg+src+onerror%3Dalert%28document.domain%29%3E+%3Cimg+src+onerror%3Dalert%28document.domain%29%3E+%3Crenniepak%40intigriti.me%3E&includeDocument=inline&message=I+wanted+to+share+this+page+with+you.`, where `<xwiki-host>` is the URL of your XWiki installation. The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.4, and 14.4.8.
