Summary
XWiki Platform has a vulnerability related to email obfuscation configuration. In versions from 3.5-milestone-1 to 14.4.8, 14.10.4, and 15.0-rc-1, server responses contained unobfuscated email addresses, allowing users to read them.
Risk Assessment
Organizations may be exposed to the disclosure of user email addresses, which could lead to unauthorized access to information and increased risk of phishing attacks.
Recommendation
It is recommended to upgrade to XWiki versions 14.4.8, 14.10.4, or 15.0-rc-1 to mitigate this vulnerability.
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. Starting in version 3.5-milestone-1 and prior to versions 14.4.8, 14.10.4, and 15.0-rc-1, the mail obfuscation configuration was not fully taken into account. While the mail displayed to the end user was obfuscated, the rest response was also containing the mail unobfuscated and users were able to filter and sort on the unobfuscated, allowing them to infer the mail content. The consequence was the possibility to retrieve the email addresses of all users even when obfuscated. This has been patched in XWiki 14.4.8, 14.10.4, and 15.0-rc-1.
