CVE-2026-54668Kitodo.Production: XXE in XMLUtils EAD/XML upload parsers (parseXMLString / getNumberOfEADElements / checkIfXmlIsWellFormed lack secure JAXP config)
High 8.7
In plain English
A high-severity XML external entity in kitodo-production from kitodo. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 23% of all known vulnerabilities).
Official description
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.
