• CVE-2025-32973: 0.41% estimated exploitation activity in the next 30 days; percentile 35.19 (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 When a user with programming right edits a document in XWiki that was last edited by a user without programming right and contains an XWiki.ComponentClass, there is no warning that this will grant programming right to this object. An attacker who created such a malicious object could use this to gain programming right on the wiki. For this, the attacker needs to have edit right on at least one page to place this object and then get an admin user to edit that document. To reproduce the problem, as a user without programming right, add an object of type XWiki.ComponentClass to any page and then edit the page as a user with programming right. There should be warning displayed, if not, the XWiki installation is vulnerable. While such a warning didn't exist in any version of XWiki, only in XWiki 15.9 RC1 these kinds of warnings have been introduced which is why this is considered the first version that has this vulnerability. Before that, the advice was to be careful when editing…

# Patch Next advisory brief: CVE-2025-32973

Advisory: org.xwiki.platform:xwiki-platform-component-wiki provides no warning when granting XWiki.ComponentClass programming right
IDs: CVE-2025-32973, GHSA-x7wv-5qg4-vmr6
Record: https://patchnext.com/advisories/cve-2025-32973 (revision 1, source checked 26 Oct 2026, 16:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.0)
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-component-wiki 16.8.0-rc-1, 16.4.3, 15.10.12. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.platform:xwiki-platform-component-wiki: affected >= 15.9-rc-1, < 15.10.12; >= 16.0.0-rc-1, < 16.4.3; >= 16.5.0-rc-1, < 16.8.0-rc-1; fixed in 16.4.3, 16.8.0-rc-1, 15.10.12

## Suggested inspection (read-only)
- Maven org.xwiki.platform:xwiki-platform-component-wiki: 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-component-wiki.
- 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
