Common Weakness Enumeration
CWE-611
AllowedImproper Restriction of XML External Entity Reference
Abstraction: Base · Status: Draft
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
558 vulnerabilities reference this CWE, most recent first.

Title
mapfish-print: XXE on MapFish Print allows reading arbitrary files of certain types
Summary
mapfish-print is a component of MapFish for printing templated cartographic maps. Prior to 3.28.30, 3.30.32, 3.31.24, 3.33.16, and 4.0.5, MapFish Print accepts an attacker-controlled GML layer url in requests to the /api/print3/print endpoint and fetches XML parsed by core/src/main/java/org/mapfish/print/map/geotools/GmlLayer.java without disabling external entities and external DTDs. A remote XML document and DTD can expand a local file entity, and the resulting content can be exposed through the GML parsing and error path. This allows unauthenticated attackers to read files such as operating-system account data, Kubernetes service-account tokens, and certificates. Replacing the file entity target with an internal HTTP endpoint also permits server-side request forgery. This issue is fixed in versions 3.28.30, 3.30.32, 3.31.24, 3.33.16, and 4.0.5.

Title
HAPI FHIR: XXE in XsltUtilities.saxonTransform via unhardened Saxon TransformerFactory
Summary
HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.10, org.hl7.fhir.utilities.XsltUtilities saxonTransform(...) overloads instantiated a bare net.sf.saxon.TransformerFactoryImpl() without ACCESS_EXTERNAL_DTD or ACCESS_EXTERNAL_STYLESHEET restrictions, allowing an attacker who controls or can tamper with transformed XML to trigger XML External Entity injection for local file disclosure and blind XXE or SSRF to arbitrary URLs reachable from the host. This issue is fixed in version 6.9.10.

Title
Kitodo.Production: XXE in XMLUtils EAD/XML upload parsers (parseXMLString / getNumberOfEADElements / checkIfXmlIsWellFormed lack secure JAXP config)
Summary
Kitodo.Production is a workflow management tool for mass digitization and is part of the Kitodo Digital Library Suite. Prior to version 3.9.2, org.kitodo.production.helper.XMLUtils exposes several XML parsing helpers that construct a JAXP parser with the default, non-secure configuration. The methods parseXMLString(String), getNumberOfEADElements(String, String) and checkIfXmlIsWellFormed(String) build a DocumentBuilderFactory / XMLInputFactory / SAXParserFactory via newInstance() and parse the attacker-supplied string without disabling DOCTYPE declarations or external entity resolution. These helpers sit directly on the EAD-import path: an authenticated user who uploads an EAD/XML file through the "Create process" file-upload dialog has the uploaded bytes parsed by these methods. A crafted document with an external entity therefore yields XML External Entity (XXE) injection: local file disclosure and outbound SSRF requests from the server. This issue has been patched in version 3.9.2.

A crafted document with an external entity therefore yields XML External Entity (XXE) injection: local file disclosure and outbound SSRF requests from the server.

Title
OpenRemote: XXE in KNXProtocol.startAssetImport() allows arbitrary file read via unprotected XMLInputFactory
Summary
OpenRemote is an open-source internet-of-things platform. Prior to 1.24.2, the KNXProtocol.startAssetImport method in agent/src/main/java/org/openremote/agent/protocol/knx/KNXProtocol.java processes 0.xml from an authenticated user's uploaded ETS project ZIP with Saxon TransformerFactoryImpl and XMLInputFactory parsers that permit external entity resolution. This incomplete remediation of CVE-2026-40882 leaves the KNX handler unprotected while the parallel Velbus handler is hardened, allowing a regular realm user to read files accessible to the JVM process or cause server-side requests. This issue is fixed in version 1.24.2.

Title
CentreStack < 17.4 XXE via SharePoint Storage Configuration
Summary
CentreStack before 17.4 contains an XML external entity (XXE) injection vulnerability that allows unauthenticated attackers to exfiltrate arbitrary files by supplying a malicious URL to the SharePoint storage configuration handler. Attackers can send a crafted request to the unauthenticated StorageConfig endpoint causing the server to fetch and parse attacker-controlled XML containing external DTD references, resulting in out-of-band file exfiltration of sensitive files such as Web.config, which may contain database credentials and cryptographic key material.

Title
veraPDF-validatio: Use of Default `DocumentBuilderFactory` leads to XXE When Processing Untrusted PDFs
Summary
veraPDF validation model is an implementation of the veraPDF validation model. From 1.25.73 until 1.30.2 and 1.31.71, veraPDF-validation contains an XML External Entity vulnerability in PDFAValidator.validate(...) and GFPDAcroForm.getdynamicRender(), where default DocumentBuilderFactory parsing of rich-text annotation or form-field values and XFA configurations in untrusted PDFs can allow local file disclosure and outbound network requests. This issue is fixed in versions 1.30.2 and 1.31.71.

Title
veraPDF Validation XXE via XFA
Summary
veraPDF validation provides PDF/A and PDF/UA validation, feature reporting, and metadata repair. From 1.17.35 until 1.30.2 and 1.31.71, veraPDF-validation contains an XML External Entity (XXE) vulnerability in validation-model/src/main/java/org/verapdf/gf/model/impl/pd/GFPDAcroForm.java in the getdynamicRender() method, where a crafted PDF containing a malicious XFA stream can cause external entity expansion during PDF/UA-1 validation and allow local file disclosure or outbound server-side requests. This issue is fixed in versions 1.30.2 and 1.31.71.

Title
Apache CXF: XML External Entity (XXE) Injection in W3CMultiSchemaFactory and EndpointReferenceUtils
Summary
Apache CXF's EndpointReferenceUtils and W3CMultiSchemaFactory classes construct a SAXParserFactory without the necessary JAXP hardening configurations, enabling out-of-band (OOB)
external entity resolution. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fix this issue.

Mitigation
Implementation
System Configuration
Many XML parsers and validators can be configured to disable external entity expansion.
CAPEC-221: Data Serialization External Entities Blowup
This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
