How severe is CVE-2023-46732?

CVE-2023-46732 has a CVSS score of 9.6/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by CVE-2023-46732?

CVE-2023-46732 affects the following packages: org.xwiki.platform:xwiki-platform-flamingo-skin-resources (Maven), org.xwiki.platform:xwiki-platform-flamingo-skin-resources (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-46732?

Update org.xwiki.platform:xwiki-platform-flamingo-skin-resources to 14.10.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-46732 is resolved across your whole dependency graph.

How do I detect CVE-2023-46732 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-flamingo-skin-resources, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2023-46732 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2023-46732 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2023-46732, 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-2023-46732?

CVE-2023-46732 has an EPSS (Exploit Prediction Scoring System) score of 2.2%, placing it in the 82th 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-2023-46732?

CVE-2023-46732 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Is there exploit tooling available for CVE-2023-46732?

A Nuclei detection template exists for CVE-2023-46732, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2023-46732 published, and has it been updated?

CVE-2023-46732 was published on November 6, 2023 and was last updated on October 28, 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

Impact

XWiki is vulnerable to reflected cross-site scripting (RXSS) via the rev parameter that is used in the content of the content menu without escaping. If an attacker can convince a user to visit a link with a crafted parameter, this allows the attacker to execute arbitrary actions in the name of the user, including remote code (Groovy) execution in the case of a user with programming right, compromising the confidentiality, integrity and availability of the whole XWiki installation.

The vulnerability can be demonstrated by opening <xwiki-host>/xwiki/bin/view/Main/?rev=xar%3Aorg.xwiki.platform%3Axwiki-platform-distribution-flavor-common%2F15.5%25%25%22%3e%3cscript%3ealert(1)%3c%2fscript%3e where <xwiki-host> is the URL of your XWiki installation. If an alert is displayed, the installation is vulnerable.

Patches

This has been patched in XWiki 15.6 RC1, 15.5.1 and 14.10.14.

Workarounds

The patch can be manually applied without upgrading (or restarting) the instance.
