Any user can call a REST endpoint and obtain the obfuscated passwords (even when the mail obfuscation is activated).

For instance, by calling http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/XWiki/pages/U1/objects/XWiki.XWikiUsers/0 when user U1 exists on wiki xwiki.

CVE-2023-35151 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. 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, 14.10.6, 15.1); upgrading removes the vulnerable code path.

1. What is CVE-2023-35151? CVE-2023-35151 is a high-severity security vulnerability in org.xwiki.platform:xwiki-platform-rest-server (maven), affecting versions >= 7.3-milestone-1, < 14.4.8. It is fixed in 14.4.8, 14.10.6, 15.1.
2. How severe is CVE-2023-35151? CVE-2023-35151 has a CVSS score of 7.5 (High). 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-rest-server are affected by CVE-2023-35151? org.xwiki.platform:xwiki-platform-rest-server (maven) versions >= 7.3-milestone-1, < 14.4.8 is affected.
4. Is there a fix for CVE-2023-35151? Yes. CVE-2023-35151 is fixed in 14.4.8, 14.10.6, 15.1. Upgrade to this version or later.
5. Is CVE-2023-35151 exploitable, and should I be worried? Whether CVE-2023-35151 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-2023-35151 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-2023-35151?
   • Upgrade org.xwiki.platform:xwiki-platform-rest-server to 14.4.8 or later
   • Upgrade org.xwiki.platform:xwiki-platform-rest-server to 14.10.6 or later
   • Upgrade org.xwiki.platform:xwiki-platform-rest-server to 15.1 or later
