    Issue

Leshan users are impacted only if they parse untrusted DDF files (e.g. if they let external users provide their own model), in that case they MUST upgrade to fixed version. If you parse only trusted DDF file and validate only with trusted xml schema, upgrading is not mandatory. Patches This is fixed in v1.5.0 and 2.0.0-M13. Workarounds No easy way. Eventually writing your own DDFFileParser/DefaultDDFFileValidator (and so ObjectLoader) creating a DocumentBuilderFactory with : References - https://owasp.org/www-community/vulnerabilities/XMLExternalEntity(XXE)Processing - https://cheatsheetseries.owasp.org/cheatsheets/XMLExternalEntityPreventionCheatSheet.html - https://semgrep.dev/docs/cheat-sheets/java-xxe/ - https://community.veracode.com/s/article/Java-Remediation-Guidance-for-XXE

    Recommended action: Upgrade to 2.0.0-M13 (pre-release) or 1.5.0 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
