What this means
Copernik XML Factory versions prior to 0.1.2 have an improper restriction of XInclude resource resolution vulnerability, allowing disclosure of local files or internal network endpoints through server-side request forgery when parsing untrusted XML. Exploitation requires specific API usage and an untrusted XML source. The issue is fixed in version 0.1.2.
Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.Attack conditions
Exploitation requires use of one of those factory/hardening APIs, the stock JDK provider with Apache Xerces absent from the classpath, explicit setXIncludeAware(true) or the equivalent reader feature, and XML from an untrusted source.

Original source description
Read the full publisher description
Copernik XML Factory provides secure-by-default JAXP factory creation for Java. Prior to 0.1.2, Copernik XML Factory does not block XInclude resource resolution on the stock JDK provider after an application enables XInclude on a factory returned by XmlFactories.newDocumentBuilderFactory() or XmlFactories.newSAXParserFactory(), or on an XMLReader passed through XmlFactories.harden(). An application parsing untrusted XML can resolve attacker-controlled xi:include references to disclose local files or, through http references, reach internal network endpoints by server-side request forgery. Exploitation requires use of one of those factory/hardening APIs, the stock JDK provider with Apache Xerces absent from the classpath, explicit setXIncludeAware(true) or the equivalent reader feature, and XML from an untrusted source. The Xerces provider selected when Xerces is present and the Android provider are unaffected. This issue is fixed in version 0.1.2.
