As published by the source; long descriptions are shortened.

Impact It's possible for a user without any specific right to perform script injection and remote code execution just by inserting an appropriate title when creating a new Change Request. This vulnerability is particularly critical as Change Request aims at being created by user without any particular rights. Patches The vulnerability has been fixed in Change Request 1.9.2. Workarounds It's possible to workaround the issue without upgrading by editing the document ChangeRequest.Code.ChangeRequestSheet and by performing the same change as in the commit: https://github.com/xwiki-contrib/application-changerequest/commit/7565e720117f73102f5a276239eabfe85e15cff4. References JIRA ticket: https://jira.xwiki.org/browse/CRAPP-298 Commit of the fix: https://github.com/xwiki-contrib/application-changerequest/commit/7565e720117f73102f5a276239eabfe85e15cff4 For more information If you have any questions or comments about this advisory: Open an issue in Jira XWiki.org Email us at Security Mailing…

# Patch Next advisory brief: CVE-2023-45138

Advisory: XWiki Change Request Application UI XSS and remote code execution through change request title
IDs: CVE-2023-45138, GHSA-f776-w9v2-7vfj
Record: https://patchnext.com/advisories/cve-2023-45138 (revision 1, source checked 26 Oct 2026, 16:19 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 10.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.xwiki.contrib.changerequest:application-changerequest-ui 1.9.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.contrib.changerequest:application-changerequest-ui: affected >= 0.11, < 1.9.2; fixed in 1.9.2

## Suggested inspection (read-only)
- Maven org.xwiki.contrib.changerequest:application-changerequest-ui: 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.contrib.changerequest:application-changerequest-ui.
- 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-f776-w9v2-7vfj (GitHub-reviewed advisory GHSA-f776-w9v2-7vfj lists affected ranges: Maven org.xwiki.contrib.changerequest:application-changerequest-ui >=0.11 <1.9.2)
