Invicti identified a session cookie not marked as secure, and transmitted over HTTPS.

This means the cookie could potentially be stolen by an attacker who can successfully intercept the traffic, following a successful man-in-the-middle attack.

It is important to note that Invicti inferred from the its name that the cookie in question is session related.

This cookie will be transmitted over a HTTP connection, therefore an attacker might intercept it and hijack a victim's session. If the attacker can carry out a man-in-the-middle attack, he/she can force the victim to make an HTTP request to your website in order to steal the cookie.

Mark all cookies used within the application as secure.

1. See the remedy for solution.
2. Mark all cookies used within the application as secure. (If the cookie is not related to authentication or does not carry any personal information, you do not have to mark it as secure.)
