The Community Events WordPress plugin before 1.6.0 does not have authorisation or nonce checks when processing public event submissions, and does not escape several of the submitted values before outputting them in the administration dashboard and on the public calendar, allowing unauthenticated users to inject arbitrary web scripts that will execute in the browser of an administrator reviewing the submission.
