Cross site scripting in Silverpeas Core
CVE-2024-56923GHSA-788m-27g4-cf86
What to do
Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.silverpeas.core:silverpeas-core 6.4.2), 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.

Source description
As published by the source; long descriptions are shortened.
Stored Cross-Site Scripting (XSS) Vulnerability in the Categorization Option of My Subscriptions Functionality in Silverpeas Core 6.3.1 <= 6.4.1 allows a remote attacker to execute arbitrary JavaScript code. This is achieved by injecting a malicious payload into the Name field of a subscription. The attack can lead to session hijacking, data theft, or unauthorized actions when an admin user views the affected subscription.

# Patch Next advisory brief: CVE-2024-56923 Advisory: Cross site scripting in Silverpeas Core IDs: CVE-2024-56923, GHSA-788m-27g4-cf86 Record: https://patchnext.com/advisories/cve-2024-56923 (revision 1, source checked 26 Oct 2026, 16:34 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: Medium (CVSS 6.9) 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 6.4.2. A vendor fix does not mean a deployment is fixed. ## Affected components - Maven org.silverpeas.core:silverpeas-core: affected >= 6.3.1, < 6.4.2; fixed in 6.4.2 ## Suggested inspection (read-only) - Maven org.silverpeas.core:silverpeas-core: 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. - 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-788m-27g4-cf86 (GitHub-reviewed advisory GHSA-788m-27g4-cf86 lists affected ranges: Maven org.silverpeas.core:silverpeas-core >=6.3.1 <6.4.2) Commands are suggestions: review each one before running it.
