Broken access control in Silverpeas

CVE-2023-47327GHSA-vpp3-hpcm-v944

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.silverpeas.core:silverpeas-core-web 6.3.2), 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-2023-47327

Advisory: Broken access control in Silverpeas
IDs: CVE-2023-47327, GHSA-vpp3-hpcm-v944
Record: https://patchnext.com/advisories/cve-2023-47327 (revision 1, source checked 26 Oct 2026, 16:21 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.silverpeas.core:silverpeas-core-web 6.3.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.silverpeas.core:silverpeas-core-web: affected < 6.3.2; fixed in 6.3.2

## Suggested inspection (read-only)
- Maven org.silverpeas.core:silverpeas-core-web: 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.silverpeas.core:silverpeas-core-web.
- 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-vpp3-hpcm-v944 (GitHub-reviewed advisory GHSA-vpp3-hpcm-v944 lists affected ranges: Maven org.silverpeas.core:silverpeas-core-web >=0 <6.3.2)

Commands are suggestions: review each one before running it.
