The Kirki WordPress plugin prior to version 6.0.12 is vulnerable due to inadequate sanitization and escaping of the email subject and body inputs. This flaw enables unauthorized users to inject arbitrary HTML code into the password-reset emails sent to registered users, thereby exposing them to potential phishing attacks. It's critical for WordPress developers and site administrators to update to the latest version to mitigate this risk and protect user data.
