How severe is CVE-2022-23622?

CVE-2022-23622 has a CVSS score of 7.4/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2022-23622?

CVE-2022-23622 affects the following packages: org.xwiki.platform:xwiki-platform-web-templates (Maven), org.xwiki.platform:xwiki-platform-web-templates (Maven), org.xwiki.platform:xwiki-platform-web-templates (Maven). Ecosystems affected: Maven.

How do I fix CVE-2022-23622?

Update org.xwiki.platform:xwiki-platform-web-templates to 12.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-23622 is resolved across your whole dependency graph.

How do I detect CVE-2022-23622 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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2022-23622 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-2022-23622 actively exploited in the wild?

No public exploit code has been indexed for CVE-2022-23622 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-2022-23622?

CVE-2022-23622 has an EPSS (Exploit Prediction Scoring System) score of 1.0%, placing it in the 62th 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-2022-23622?

Description

Impact

We found a possible XSS vector in the registerinline.vm template related to the xredirect hidden field. This template is only used in the following conditions:

the wiki must be open to registration for anyone
the wiki must be closed to view for Guest users (more specifically the XWiki.Registration page must be forbidden in View for guest user)

A way to obtain the second condition is when administrators checked the "Prevent unregistered users from viewing pages, regardless of the page rights" box in the administration rights.

Patches

The issue is patched in versions 12.10.11, 14.0-rc-1, 13.4.7, 13.10.3.

Workarounds

There are two main ways for protecting against this vulnerability, the easiest and the best one is by applying a patch in the registerinline.vm template, the patch consists in checking the value of the xredirect field to ensure it matches the following:

<input type="hidden" name="xredirect" value="$escapetool.xml($!request.xredirect)" />

If for some reason it's not possible to patch this file, another workaround is to ensure "Prevent unregistered users from viewing pages, regardless of the page rights" is not checked in the rights and apply a better right scheme using groups and rights on spaces.
