Affected versions of this package are vulnerable to Improper Neutralization of Special Elements Used in a Template Engine via the render_template method. An attacker can execute arbitrary commands with the privileges of the running process by injecting malicious payloads into data fields that are rendered by trusted templates.
Note: This is only exploitable if attacker-controlled input data is rendered into a trusted template and the user/operator processes the attacker-controlled data, such as SSP or LUT files.
