Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
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.
