Eclipse Rdf4J
Monthly
XXE injection in Eclipse RDF4J exposes applications to local file disclosure and server-side request forgery when parsing untrusted XML-based RDF data or SPARQL query results. The root cause is an incomplete remediation of CVE-2018-1000644: while that earlier fix hardened some parser entry points, several XML parser interfaces remained unprotected against DOCTYPE declarations, external entity references, and external DTD loading. No public exploit has been identified at time of analysis, and no CISA KEV listing exists, but the unauthenticated network vector (CVSS 4.0: 8.7, PR:N) means any application exposing RDF ingestion endpoints is at risk without upgrading to RDF4J 5.3.2.
