Impact
Any user with edit right can execute arbitrary database select and access data stored in the database.
To reproduce:
- In admin, rights, remove scripting rights for {{XWikiAllGroup}}.
- Create a new user without any special privileges.
- Create a page "Private.WebHome" with {{TOKEN_42}} as content. Go to "page administration" and explicitly set all rights for "Admin" to remove them for all other users.
- Logout and login as the unprivileged user. Ensure that the previously created page cannot be viewed.
- Create a new page "ExploitClass.WebHome" and then open it in the class editor (first, make the user an advanced user).
- Add a field named {{ContentList}} of type {{Database List}}
- Enter in field "Hibernate Query" the following content: {noformat}select doc.content, doc.fullName from XWikiDocument as doc where doc.fullName = 'Private.WebHome'{noformat}
- Save the class.
- Open [http://localhost:8080/xwiki/bin/view/ExploitClass/?xpage=suggest&classname=ExploitClass.WebHome&fieldname=ContentList&firCol=doc.fullName&secCol=-]
CVE-2023-26473 has a CVSS score of 6.5 (Medium). The vector is network-reachable, low 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 (13.10.11, 14.4.7, 14.10); upgrading removes the vulnerable code path.

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.

Frequently Asked Questions
- What is CVE-2023-26473? CVE-2023-26473 is a medium-severity security vulnerability in org.xwiki.platform:xwiki-platform-web (maven), affecting versions >= 1.3-rc-1, < 13.10.11. It is fixed in 13.10.11, 14.4.7, 14.10.
- How severe is CVE-2023-26473? CVE-2023-26473 has a CVSS score of 6.5 (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.
- Which versions of org.xwiki.platform:xwiki-platform-web are affected by CVE-2023-26473? org.xwiki.platform:xwiki-platform-web (maven) versions >= 1.3-rc-1, < 13.10.11 is affected.
- Is there a fix for CVE-2023-26473? Yes. CVE-2023-26473 is fixed in 13.10.11, 14.4.7, 14.10. Upgrade to this version or later.
- Is CVE-2023-26473 exploitable, and should I be worried? Whether CVE-2023-26473 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-2023-26473 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.
