The CVE record names the fixed release — apply it.

XML External Entity (XXE) Injection in ContentWorker in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote authenticated attacker holding content-author permission to read arbitrary server files and trigger server-side request forgery by storing a crafted text/xml DataResource containing an external entity declaration, causing ContentWorker's rendering of that content — via renderContentAsText and related CMS/help render paths — to parse the stored XML using FreeMarker's default NodeModel.parse DocumentBuilderFactory, which enables neither FEATURE_SECURE_PROCESSING nor external-entity/DTD restrictions, resolving the external entity and returning its content in the rendered response. Users are recommended to upgrade to version 24.09.08, which fixes this issue.
