How severe is CVE-2023-47324?

CVE-2023-47324 has a CVSS score of 5.4/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2023-47324?

CVE-2023-47324 affects the following packages: org.silverpeas.core:silverpeas-core-web (Maven), org.silverpeas.core:silverpeas-core-api (Maven), org.silverpeas.core:silverpeas-core-war (Maven), org.silverpeas.core:silverpeas-core-configuration (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-47324?

Update org.silverpeas.core:silverpeas-core-web to 6.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-47324 is resolved across your whole dependency graph.

How do I detect CVE-2023-47324 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.silverpeas.core:silverpeas-core-web, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2023-47324 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2023-47324 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2023-47324, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2023-47324?

CVE-2023-47324 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 41th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2023-47324?
