Issue reported by Lukas Monert.

Anyone can access the metadata of any attachment in the wiki using the wiki attachment REST endpoint. It's not filtering the result depending on current user rights, a not authenticated user could exploit this even in a totally private wiki.

To reproduce:

• remove view from guest on the whole wiki
• logout
• access http://127.0.0.1:8080/xwiki/rest/wikis/xwiki/spaces/Sandbox/pages/WebHome/attachments

You get a list of attachments, while the expected result should be an empty list.

The application does not perform an authorization check before performing a sensitive operation. Typical impact: unauthorized access to restricted functionality or data.

CVE-2025-46554 has a CVSS score of 5.3 (Medium). 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 (14.10.22, 15.10.12, 16.4.3, 16.7.0); upgrading removes the vulnerable code path.

This vulnerability has been fixed in XWiki 14.10.22, 15.10.12, 16.7.0-rc-1 and 16.4.3.

1. What is CVE-2025-46554? CVE-2025-46554 is a medium-severity missing authorization vulnerability in org.xwiki.platform:xwiki-platform-rest-server (maven), affecting versions >= 1.8.1, < 14.10.22. It is fixed in 14.10.22, 15.10.12, 16.4.3, 16.7.0. The application does not perform an authorization check before performing a sensitive operation.
2. How severe is CVE-2025-46554? CVE-2025-46554 has a CVSS score of 5.3 (Medium). 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-2025-46554? org.xwiki.platform:xwiki-platform-rest-server (maven) versions >= 1.8.1, < 14.10.22 is affected.
4. Is there a fix for CVE-2025-46554? Yes. CVE-2025-46554 is fixed in 14.10.22, 15.10.12, 16.4.3, 16.7.0. Upgrade to this version or later.
5. Is CVE-2025-46554 exploitable, and should I be worried? Whether CVE-2025-46554 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-2025-46554 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-2025-46554?
   • Upgrade org.xwiki.platform:xwiki-platform-rest-server to 14.10.22 or later
