## Core 1.2.1 Release Notes {#core-v1-2-1}

**February 9, 2017** &mdash; Sensu Core version 1.2.1 has been
	released and is available for immediate download. Please note
	the following improvements:

### CHANGES {#core-v1-2-1-changes}

- **SECURITY FIX**: Sensu's configuration redaction function failed to
  handle key/value pairs in deeply nested data structures, resulting in
  sensitive configuration data (e.g. passwords) being logged in clear-text.
  The redaction function now handles the necessary recursion to address
  this vulnerability.

  This vulnerability is documented as [CVE-2018-1000060](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-1000060).
