What is CVE-2026-73244?

In kkFileView, a file preview project implemented with Spring Boot, a security oversight prior to version 5.0.1 allows unauthenticated users to exploit the /listFiles endpoint. The user-controlled path parameter is passed to the file handling method without proper confinement, enabling attackers to enumerate directories beyond the intended demo directory. This vulnerability underscores the need for stringent access controls and input validation to secure file handling processes. The issue has been addressed in version 5.0.1.

Affected Version(s)

kkFileView < 5.0.1
