Insecure cookie setting: missing Secure flag

-
  Issue Description: Insecure Cookie Setting - Missing Secure Flag Explanation: The "Secure" flag is an attribute that can be set for cookies in web applications. When the Secure flag is enabled for a cookie, the cookie is only transmitted over HTTPS connections, ensuring that it is sent securely over an encrypted channel. This is crucial for security because it helps prevent the exposure of sensitive information contained in cookies, such as session tokens or authentication credentials, to potential attackers. When the Secure flag is missing from a cookie, it means that the cookie can be sent over both secure (HTTPS) and non-secure (HTTP) connections. This can pose a significant security risk, as sensitive information could be exposed if the cookie is transmitted over an insecure connection. Impact: The impact of missing the Secure flag on a cookie depends on the context in which the cookie is used. Here are some potential risks: Session Hijacking: If an attacker can inter
