Which packages are affected by CVE-2025-23025?

CVE-2025-23025 affects the following packages: org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui (Maven), org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui (Maven), org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui (Maven). Ecosystems affected: Maven.

How do I fix CVE-2025-23025?

Update org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui to 15.10.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-23025 is resolved across your whole dependency graph.

How do I detect CVE-2025-23025 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2025-23025 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2025-23025?

O3 pinpoints whether CVE-2025-23025 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2025-23025 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-23025 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-23025?

CVE-2025-23025 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 31th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2025-23025?

CVE-2025-23025 is classified as CWE-862 (CWE-862). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2025-23025 published, and has it been updated?

CVE-2025-23025 was published on January 14, 2025 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. NOTE: The Realtime WYSIWYG Editor extension was experimental, and thus not recommended, in the versions affected by this vulnerability. It has become enabled by default, and thus recommended, starting with XWiki 16.9.0. A user with only edit right can join a realtime editing session where others, that where already there or that may join later, have script or programming access rights. This user can then insert script rendering macros that are executed for those users in the realtime session that have script or programming rights. The inserted scripts can be used to gain more access rights. This vulnerability has been patched in XWiki 15.10.2, 16.4.1 and 16.6.0-rc-1. Users are advised to upgrade. Users unable to upgrade may either disable the realtime WYSIWYG editing by disabling the xwiki-realtime CKEditor plugin from the WYSIWYG editor administration section or uninstall the Realtime WYSIWYG Editorextension (org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui).
