Summary
The Kirki WordPress plugin before version 6.0.12 does not sanitize or escape the email subject and body values supplied in a request before including them in the password-reset email sent as HTML. This allows unauthenticated users to inject arbitrary HTML into the message delivered to a registered user, which can be used for phishing.
Risk Assessment
An attacker can craft a password reset request that sends an email with arbitrary HTML, such as a fake login form, to the victim. This increases the risk of credential theft and WordPress user account compromise.
Recommendation
Immediately update the Kirki plugin to version 6.0.12 or later. If an update is not possible, consider temporarily disabling the plugin until it can be updated.
