CVE-2023-45134 has a CVSS score of 9/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by CVE-2023-45134?

CVE-2023-45134 affects the following packages: org.xwiki.platform:xwiki-platform-web-templates (Maven), org.xwiki.platform:xwiki-platform-web-templates (Maven), org.xwiki.platform:xwiki-web-standard (Maven), org.xwiki.platform:xwiki-platform-web (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-45134?

Update org.xwiki.platform:xwiki-platform-web-templates to 14.10.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-45134 is resolved across your whole dependency graph.

How do I detect CVE-2023-45134 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-web-templates. 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-2023-45134 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-2023-45134?

O3 pinpoints whether CVE-2023-45134 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-2023-45134 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2023-45134, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2023-45134?

CVE-2023-45134 has an EPSS (Exploit Prediction Scoring System) score of 1.8%, placing it in the 76th 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.

When was CVE-2023-45134 published, and has it been updated?

CVE-2023-45134 was published on October 25, 2023 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. org.xwiki.platform:xwiki-platform-web starting in version 3.1-milestone-1 and prior to 13.4-rc-1, org.xwiki.platform:xwiki-platform-web-templates prior to versions 14.10.2 and 15.5-rc-1, and org.xwiki.platform:xwiki-web-standard starting in version 2.4-milestone-2 and prior to version 3.1-milestone-1 are vulnerable to cross-site scripting. An attacker can create a template provider on any document that is part of the wiki (could be the attacker's user profile) that contains malicious code. This code is executed when this template provider is selected during document creation which can be triggered by sending the user to a URL. For the attacker, the only requirement is to have an account as by default the own user profile is editable. This allows an attacker to execute arbitrary actions with the rights of the user opening the malicious link. Depending on the rights of the user, this may allow remote code execution and full read and write access to the whole XWiki installation. This has been patched in org.xwiki.platform:xwiki-platform-web 13.4-rc-1, org.xwiki.platform:xwiki-platform-web-templates 14.10.2 and 15.5-rc-1, and org.xwiki.platform:xwiki-web-standard 3.1-milestone-1 by adding the appropriate escaping. The vulnerable template file createinline.vm is part of XWiki's WAR and can be patched by manually applying the changes from the fix.
