CVE-2022-36093 has a CVSS score of 8.5/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2022-36093?

CVE-2022-36093 affects the following packages: org.xwiki.platform:xwiki-platform-web-templates (Maven), org.xwiki.platform:xwiki-platform-web (Maven), org.xwiki.platform:xwiki-platform-web-templates (Maven), org.xwiki.platform:xwiki-platform-web (Maven). Ecosystems affected: Maven.

How do I fix CVE-2022-36093?

Update org.xwiki.platform:xwiki-platform-web-templates to 13.10.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-36093 is resolved across your whole dependency graph.

How do I detect CVE-2022-36093 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-2022-36093 if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is CVE-2022-36093 actively exploited in the wild?

No public exploit code has been indexed for CVE-2022-36093 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.

Description

Impact

By passing a template of the distribution wizard to the xpart template, user accounts can be created even when user registration is disabled. This also circumvents any email verification. Before versions 14.2 and 13.10.4, this can also be exploited on a private wiki, thus potentially giving the attacker access to the wiki. Depending on the configured default rights of users, this could also give attackers write access to an otherwise read-only public wiki. Users can also be created when an external authentication system like LDAP is configured, but authentication fails unless the authentication system supports a bypass/local accounts are enabled in addition to the external authentication system.

Patches

This issue has been patched in XWiki 13.10.5 and 14.3RC1.

Workarounds

It is possible to replace xpart.vm, the entry point for this attack, by a patched version from the patch without updating XWiki.
