Description: The Validation Component of Apache Camel evaluates DTD headers of XML stream sources, although a validation against XML schemas (XSD) is executed. Remote attackers can use this feature to make Server-Side Request Forgery (SSRF) attacks by sending XML documents with remote DTDs URLs or XML External Entities (XXE). The vulnerability is not given for SAX or StAX sources.
Mitigation: 2.17.x users should upgrade to 2.17.6, 2.18.x users should upgrade to 2.18.3.
