Summary
XWiki Platform allows users to edit their profiles and notification settings, enabling the execution of arbitrary script macros, including Groovy and Python, leading to remote code execution. Versions 14.10.6 and 15.2RC1 contain patches for this vulnerability.
Risk Assessment
Organizations may be exposed to remote code execution, leading to unauthorized access to all wiki content. This poses a serious threat to the integrity and confidentiality of data.
Recommendation
It is recommended to update to version 14.10.6 or 15.2RC1. Alternatively, the patch can be manually applied to the document `XWiki.Notifications.Code.NotificationRSSService`, but this requires additional changes to Velocity templates.
Other vulnerabilities in XWiki Platform
See all- CVE-2026-33137Critical
A vulnerability in XWiki Platform versions starting with 15.10.6 and prior to 18.1.0-rc-1, 17.10.3, 17.4.9, and 16.10.17. The POST /wikis/{wikiName} API performs a XAR import without authentication or authorization checks, allowing an unauthenticated attacker to create or update documents in the target wiki.
- CVE-2026-23734Critical
A vulnerability in XWiki Platform allows reading configuration files by manipulating the resource parameter in ssx and jsx endpoints, leading to Path Traversal. Affects versions prior to 18.1.0-rc-1, 17.10.3, 17.4.9, and 16.10.17.
- CVE-2026-33229Critical
XWiki Platform is a wiki platform. Prior to versions 17.4.8 and 17.10.1, an improperly protected scripting API allows users with script right to bypass the Velocity sandbox and execute arbitrary Python scripts, leading to full access to the XWiki instance.
- CVE-2023-40573Critical
XWiki Platform has a vulnerability that allows remote code execution by an attacker with edit rights on the wiki. It exploits a flaw in the job scheduler and an issue with content author authorization. This vulnerability has been patched in XWiki versions 14.10.9 and 15.4RC1.
- CVE-2023-40572Critical
XWiki Platform is vulnerable to a CSRF attack in the create action, allowing remote code execution by users with appropriate permissions. If a user with script rights sees a specific log message, the XWiki installation is at risk.
- CVE-2023-40177Critical
XWiki Platform allows registered users to execute arbitrary scripts in the content field of their profile page, leading to rights escalation. This issue has been present since version 4.3M2 when support for the content field was added in the AppWithinMinutes application.
- CVE-2023-40176Critical
XWiki Platform has a stored XSS vulnerability that can be exploited by registered users by setting a malicious payload in the time zone user preference. Although the time zone is selected from a dropdown, it can still be set using JavaScript or the appropriate URL.
- CVE-2023-37914Critical
XWiki Platform allows users who can view `Invitation.WebHome` to execute arbitrary script macros, including Groovy and Python, leading to remote code execution. This vulnerability allows unrestricted read and write access to all wiki contents.
- CVE-2023-37462Critical
XWiki Platform has a vulnerability due to improper escaping in the `SkinsCode.XWikiSkinsSheet` document. This allows attackers to execute arbitrary script macros, including Groovy and Python, leading to remote code execution and unrestricted access to wiki content.
- CVE-2023-37277Critical
XWiki Platform has a vulnerability that allows remote code execution via a cross-site request forgery (CSRF) attack using the REST API. Exploitation of this flaw by a user with programming rights can impact the integrity, availability, and confidentiality of the entire XWiki installation.
Original NVD description (English source)
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user who can edit their own user profile and notification settings can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. This has been patched in XWiki 14.10.6 and 15.2RC1. Users are advised to update. As a workaround the main security fix can be manually applied by patching the affected document `XWiki.Notifications.Code.NotificationRSSService`. This will break the link to the differences, though as this requires additional changes to Velocity templates as shown in the patch. While the default template is available in the instance and can be easily patched, the template for mentions is contained in a `.jar`-file and thus cannot be fixed without replacing that jar.
