How to Fix CVE-2026-24128

To remediate this vulnerability, upgrade all affected Xwiki platform web templates dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.xwiki.platform:xwiki-platform-web-templates fixed: 16.10.12
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-web-templates</artifactId>
    <version>16.10.12</version>
</dependency>
org.xwiki.platform:xwiki-platform-web-templates fixed: 17.4.5
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-web-templates</artifactId>
    <version>17.4.5</version>
</dependency>
org.xwiki.platform:xwiki-platform-web-templates fixed: 17.8.0-rc-1
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-web-templates</artifactId>
    <version>17.8.0-rc-1</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

mvn dependency:tree -Dincludes=org.xwiki.platform

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-24128, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.xwiki.platform

Analyze the terminal output to locate any version of Xwiki platform web templates in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 16.10.12), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.xwiki.platform command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS), where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. In Xwiki platform web templates, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact A reflected cross site scripting (XSS) vulnerability in XWiki allows an attacker to execute arbitrary actions in XWiki with the rights of the victim if the attacker manages to trick a victim into visiting a crafted URL. If the victim has administrative or programming rights, those rights can be exploited to gain full access to the XWiki installation. ### Patches This vulnerability has been patched in XWiki 17.8.0RC1, 17.4.5 and 16.10.12. ### Workarounds The [patch](https://github.com/xwiki/xwiki-platform/commit/8337ac8c3b19c37f306723b638b2cae8b0a57dbf#diff-8f16efedd19baae025db602d8736a105bfd8f72676af2c935b8195a0c356ee71) can be applied manually, only a single line in `templates/logging_macros.vm` needs to be changed, no restart is required. ### References * https://github.com/xwiki/xwiki-platform/commit/8337ac8c3b19c37f306723b638b2cae8b0a57dbf * https://jira.xwiki.org/browse/XWIKI-23462 ### Attribution We thank Mike Cole @mikecole-mg for discovering and reporting this vulnerability.
