Impact
The title of every single page whose reference is known can be accessed through the REST API as long as an XClass with a page property is accessible, this is the default for an XWiki installation. This allows an attacker to get titles of pages whose reference is known, one title per request. This doesn't affect fully private wikis as the REST endpoint checks access rights on the XClass definition. The impact on confidentiality depends on the strategy for page names. By default, page names match the title, so the impact should be low but if page names are intentionally obfuscated because the titles are sensitive, the impact could be high.

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 has been fixed in XWiki 16.4.7, 16.10.3 and 17.0.0 by adding access control checks before getting the title of any page.
Frequently Asked Questions
- What is CVE-2025-49584? CVE-2025-49584 is a high-severity security vulnerability in org.xwiki.platform:xwiki-platform-rest-server (maven), affecting versions >= 10.9, < 16.4.7. It is fixed in 16.4.7, 16.10.3, 17.0.0.
- Which versions of org.xwiki.platform:xwiki-platform-rest-server are affected by CVE-2025-49584? org.xwiki.platform:xwiki-platform-rest-server (maven) versions >= 10.9, < 16.4.7 is affected.
- Is there a fix for CVE-2025-49584? Yes. CVE-2025-49584 is fixed in 16.4.7, 16.10.3, 17.0.0. Upgrade to this version or later.
- Is CVE-2025-49584 exploitable, and should I be worried? Whether CVE-2025-49584 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-2025-49584 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.
