How severe is CVE-2023-35161?

CVE-2023-35161 has a CVSS score of 9.6/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by CVE-2023-35161?

CVE-2023-35161 affects the following packages: org.xwiki.platform:xwiki-platform-appwithinminutes-ui (Maven), org.xwiki.platform:xwiki-platform-appwithinminutes-ui (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-35161?

Update org.xwiki.platform:xwiki-platform-appwithinminutes-ui to 14.10.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-35161 is resolved across your whole dependency graph.

How do I detect CVE-2023-35161 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-appwithinminutes-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2023-35161 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-2023-35161 actively exploited in the wild?

No public exploit code has been indexed for CVE-2023-35161 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-2023-35161?

CVE-2023-35161 has an EPSS (Exploit Prediction Scoring System) score of 2.4%, placing it in the 84th 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-2023-35161?

CVE-2023-35161 is classified as CWE-87 (CWE-87), Cross-site Scripting (XSS) (CWE-79). These weakness types 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-2023-35161?

A Nuclei detection template exists for CVE-2023-35161, 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-2023-35161 published, and has it been updated?

CVE-2023-35161 was published on June 23, 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

Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). It's possible to exploit the DeleteApplication page to perform a XSS, e.g. by using URL such as:

xwiki/bin/view/AppWithinMinutes/DeleteApplication?appName=Menu&resolve=true&xredirect=javascript:alert(document.domain)

This vulnerability exists since XWiki 6.2-milestone-1.

Patches

The vulnerability has been patched in XWiki 14.10.5 and 15.1-rc-1.

Workarounds

It's possible to workaround the vulnerability by editing the page AppWithinMinutes.DeleteApplication to perform checks on it, but note that the appropriate fix involves new APIs that have been recently introduced in XWiki. See the referenced jira tickets.
