Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection via the select_eval custom field type. An attacker can execute arbitrary Ruby code on the server by supplying a malicious expression in the field options command parameter, which is evaluated through instance_eval within an ERB view when a post edit page is rendered. This allows the attacker to achieve code execution with the privileges of the web server process. This is only exploitable if the attacker has permissions to manage custom fields.
