Summary
The XWiki Platform has a vulnerability that allows tags from pages not viewable to the current user to be leaked via the tags API. This information can be exploited to infer the document reference of non-viewable pages.
Risk Assessment
The disclosure of information about inaccessible pages may lead to privacy breaches and data security issues within the organization. An attacker could use this data for further malicious actions.
Recommendation
It is recommended to upgrade to XWiki versions 14.4.8, 14.10.4, or 15.0-rc-1 to mitigate this vulnerability. A data access audit should also be conducted to minimize risk.
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-2025-24893CriticalActively exploited
XWiki Platform allows any guest to perform arbitrary remote code execution through a request to `SolrSearch`. This impacts the confidentiality, integrity, and availability of the whole XWiki installation.
- 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.
