Improper Restriction of XML External Entity Reference vulnerability in Apache Camel XPath component.
This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1.
With documentType set to InputSource, XPathBuilder handed the payload straight to javax.xml.xpath, which builds a DocumentBuilder of its own using the JDK defaults. The hardening applied to Camel's default document type was therefore bypassed: a DOCTYPE declaration that is refused on the default type was accepted here, and the external entity it declared was resolved and expanded into the evaluated document. An external sender whose XML reaches such an expression could read files readable by the Camel process and cause the process to issue requests to hosts it names. The two document types disagreeing on parser configuration is what made this reachable, since a deployment choosing InputSource for streaming reasons had no indication it was also choosing a weaker parser.
Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. The InputSource document type now goes through the same hardened parser as the default type, so a DOCTYPE is refused. Note that it also shares that type's documented escape hatch: the same DocumentBuilderFactory system properties that relax the default type relax this one, so a deployment that has set them remains unprotected by design. For deployments that cannot upgrade immediately, do not use documentType=InputSource on expressions evaluated over untrusted XML; the default document type already refuses a DOCTYPE.

org.apache.camel/camel-xpath: camel-xpath: Information disclosure via XML external entity references
A flaw was found in Apache Camel's XPath component. This vulnerability can lead to information disclosure and unauthorized network requests when the component evaluates XML expressions using unhardened streaming parser configurations. A remote attacker can exploit this flaw by submitting specially crafted XML data containing external entity references, allowing them to read sensitive local files accessible to the application process or trigger outbound network requests.
