EPSS

• CVE-2022-36093: 0.89% estimated exploitation activity in the next 30 days; percentile 59.55 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2022-36093

Advisory: XWiki Platform Web Templates vulnerable to Unauthorized User Registration Through the Distribution Wizard
IDs: CVE-2022-36093, GHSA-h5j3-5x63-p8jv
Record: https://patchnext.com/advisories/cve-2022-36093 (revision 1, source checked 26 Oct 2026, 16:01 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.xwiki.platform:xwiki-platform-web 14.3-rc-1, 13.10.5; org.xwiki.platform:xwiki-platform-web-templates 14.3-rc-1, 13.10.5. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-web: affected >= 8.0-rc-1, < 13.10.5; >= 14.0, < 14.3-rc-1; fixed in 14.3-rc-1, 13.10.5
- Maven org.xwiki.platform:xwiki-platform-web-templates: affected < 13.10.5; >= 14.0, < 14.3-rc-1; fixed in 14.3-rc-1, 13.10.5

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-web: check the installed version with your package manager.
- Maven org.xwiki.platform:xwiki-platform-web-templates: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.xwiki.platform:xwiki-platform-web, org.xwiki.platform:xwiki-platform-web-templates.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-h5j3-5x63-p8jv (GitHub-reviewed advisory GHSA-h5j3-5x63-p8jv lists affected ranges: Maven org.xwiki.platform:xwiki-platform-web-templates >=0 =14.0 =8.0-rc-1 =14.0 <14.3-rc-1)
