CVE-2026-54668

Full vulnerability record from the local CVENow database.

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.
