CVE-2023-37465GHSA-4j38-rw27-97gx

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.xwiki.contrib:discussions-server 2.0-rc-1), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2023-37465

Advisory: org.xwiki.contrib:discussions-server has Cross-Site Request Forgery (CSRF) issue that makes it possible to delete messages
IDs: CVE-2023-37465, GHSA-4j38-rw27-97gx
Record: https://patchnext.com/advisories/cve-2023-37465 (revision 2, source checked 26 Oct 2026, 16:54 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.xwiki.contrib:discussions-server 2.0-rc-1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.xwiki.contrib:discussions-server: affected < 2.0-rc-1; fixed in 2.0-rc-1

## Suggested inspection (read-only)
- Maven org.xwiki.contrib:discussions-server: 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:discussions-server.
- 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.
