What is CVE-2019-10080?

The XMLFileLookupService in Apache NiFi versions from 1.3.0 to 1.9.2 is susceptible to a vulnerability that allows trusted users to unintentionally configure harmful XML files. These files can execute external service calls, potentially exposing sensitive information, including details about the Java, Jersey, and Apache versions utilized by the NiFi instance. This risk arises from the way XML parsing is handled, potentially leading to significant data leakage if exploited.
