GHSA-XM28-XVQC-GXXG

Vulnerability from github – Published: 2026-10-02 18:27 – Updated: 2026-10-02 18:27
VLAI
Summary
Copernik XML Factory (stock JDK provider) has Improper restriction of XInclude resource resolution
Details

Copernik XML Factory through 0.1.1, when running on its stock JDK provider, does not block XInclude resource resolution after an application enables XInclude on a factory returned by XmlFactories.newDocumentBuilderFactory() or XmlFactories.newSAXParserFactory(), or on an XMLReader passed through XmlFactories.harden(). The library's documented guarantee that XInclude resolution stays disabled therefore does not hold on that provider.

An application that parses untrusted XML in this configuration can be made to resolve xi:include references, allowing an attacker to read local files (information disclosure) or, through http hrefs, reach internal network endpoints (SSRF).

All of the following conditions must hold for an application to be affected: - it obtains a factory from XmlFactories.newDocumentBuilderFactory() or XmlFactories.newSAXParserFactory(), or hardens an externally obtained XMLReader with XmlFactories.harden(); - the stock JDK provider is in effect, that is, Apache Xerces is not on the classpath; - XInclude is enabled, by calling setXIncludeAware(true) or the equivalent reader feature; - it parses XML from an untrusted source.

The Xerces provider (selected when Xerces is on the classpath) and the Android provider are not affected.

Applications are advised to upgrade to 0.1.2, which fixes the defect. As a workaround add Apache Xerces (xercesImpl) to the classpath so the library selects its unaffected Xerces provider.

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.
