It's possible to execute javascript with the right of any user by leading him to a special URL on the wiki targeting a page which contains an attachment.

To reproduce:

• add an attachment to a page (for example, your user profile)
• add ?xpage=importinline&editor=%22%3E%3Cimg%20src%20onerror=alert(document.domain)%3E to the page view URL as in https://myhost/xwiki/bin/view/XWiki/MyUser?xpage=importinline&editor=%22%3E%3Cimg%20src%20onerror=alert(document.domain)%3E

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.

CVE-2023-32071 has a CVSS score of 9.0 (Critical). The vector is network-reachable, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (14.4.8, 14.10.4); upgrading removes the vulnerable code path.

1. What is CVE-2023-32071? CVE-2023-32071 is a critical-severity cross-site scripting (XSS) vulnerability in org.xwiki.platform:xwiki-platform-distribution-war (maven), affecting versions >= 2.2-milestone-1, < 14.4.8. It is fixed in 14.4.8, 14.10.4. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
2. How severe is CVE-2023-32071? CVE-2023-32071 has a CVSS score of 9.0 (Critical). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of org.xwiki.platform:xwiki-platform-distribution-war are affected by CVE-2023-32071? org.xwiki.platform:xwiki-platform-distribution-war (maven) versions >= 2.2-milestone-1, < 14.4.8 is affected.
4. Is there a fix for CVE-2023-32071? Yes. CVE-2023-32071 is fixed in 14.4.8, 14.10.4. Upgrade to this version or later.
5. Is CVE-2023-32071 exploitable, and should I be worried? Whether CVE-2023-32071 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.

6. What actually determines whether CVE-2023-32071 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.
7. How do I fix CVE-2023-32071?
   • Upgrade org.xwiki.platform:xwiki-platform-distribution-war to 14.4.8 or later
   • Upgrade org.xwiki.platform:xwiki-platform-distribution-war to 14.10.4 or later
