AI-Generated

Eclipse RDF4J is vulnerable due to insufficient restrictions on XML External Entity (XXE) processing across several XML parser entry points, allowing for potential exploitation through untrusted XML-based RDF data. This vulnerability could lead to unauthorized access to sensitive data or server-side request forgery attacks. Organizations using affected versions of RDF4J should prioritize upgrading to version 5.3.2 or later to mitigate these risks.

Original NVD Description

In Eclipse RDF4J, several XML parser entry points do not fully restrict XML External Entity (XXE) processing when parsing untrusted XML-based RDF data or query results, permitting DOCTYPE declarations, external entity references, and external DTD loading. This is due to an incomplete fix for CVE-2018-1000644: the earlier fix did not cover all parser entry points. The issue is resolved in RDF4J 5.3.2, which rejects or disables DOCTYPE declarations, external entities, and external DTD loading by default.
