Background
Apache NiFi is a robust data integration tool designed for automating the flow of data between systems. It provides an intuitive user interface for managing data flows, enabling users to design, control, and monitor data pipelines. Despite its powerful features, versions 1.0.0 to 1.10.0 are susceptible to a cross-site scripting (XSS) vulnerability that can be exploited through the user interface.

The vulnerability identified as CVE-2020-1933 allows attackers to inject malicious scripts into the Apache NiFi user interface. This occurs when an unaware authenticated user interacts with the UI in Firefox, potentially leading to unauthorized actions or data exposure. The issue does not appear to affect other browsers, which may limit the scope of the attack but still poses a significant risk to users operating in the vulnerable environment.
