No source in this snapshot names a fixed version.

Description

The HootBoard WordPress plugin through 3.1.4 does not perform any authorisation check on some of its REST endpoints, and does not escape the values stored through them before outputting them in a public page, allowing unauthenticated users to inject arbitrary web scripts that will execute in the browser of anyone visiting that page, including administrators.
