Summary
Workarounds
The patch can be manually applied to the templates that are present in the WAR. A restart of XWiki is needed for the changes to be applied.
Impact
A reflected XSS vulnerability in XWiki allows an attacker to send a victim to a URL with a deletion confirmation message on which the attacker-supplied script is executed when the victim clicks the "No" button. When the victim has admin or programming right, this allows the attacker to execute basically arbitrary actions on the XWiki installation including remote code execution.
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
Remediation advice
This vulnerability has been patched in XWiki 16.10.10, 17.4.2 and 17.5.0 by using the affected URL parameter only in the intended context.
Frequently Asked Questions
- What is CVE-2025-66472? CVE-2025-66472 is a medium-severity cross-site scripting (XSS) vulnerability in org.xwiki.platform:xwiki-platform-flamingo-skin-resources (maven), affecting versions >= 6.2-milestone-1, < 16.10.10. It is fixed in 16.10.10, 17.4.2. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- Which packages are affected by CVE-2025-66472?
org.xwiki.platform:xwiki-platform-flamingo-skin-resources(maven) (versions >= 6.2-milestone-1, < 16.10.10)org.xwiki.platform:xwiki-platform-web-templates(maven) (versions >= 6.2-milestone-1, < 16.10.10)
- Is there a fix for CVE-2025-66472? Yes. CVE-2025-66472 is fixed in 16.10.10, 17.4.2. Upgrade to this version or later.
- Is CVE-2025-66472 exploitable, and should I be worried? Whether CVE-2025-66472 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-66472 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
