Common Weakness Enumeration
CWE-827
AllowedImproper Control of Document Type Definition
Abstraction: Variant · Status: Incomplete
The product does not restrict a reference to a Document Type Definition (DTD) to the intended control sphere. This might allow attackers to reference arbitrary DTDs, possibly causing the product to expose files, consume excessive system resources, or execute arbitrary http requests on behalf of the attacker.
3 vulnerabilities reference this CWE, most recent first.
CVE-2026-15803 (GCVE-0-2026-15803)
Vulnerability from cvelistv5 – Published: 2026-08-12 15:38 – Updated: 2026-08-13 15:22

Summary
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.

Title
XXE vulnerability in Eclipse JGit
Summary
In Eclipse JGit versions 7.2.0.202503040940-r and older, the ManifestParser class used by the repo command and the AmazonS3 class used to implement the experimental amazons3 git transport protocol allowing to store git pack files in an Amazon S3 bucket, are vulnerable to XML External Entity (XXE) attacks when parsing XML files. This vulnerability can lead to information disclosure, denial of service, and other security issues.
