Valid

Reported on

Sep 2nd 2021


✍️ Description

The secure flag is not set for session cookies in the application.

🕵️‍♂️ Proof of Concept

Cookie Without Secure Flag

💥 Impact

If the secure flag is set on a cookie, then browsers will not submit the cookie in any requests that use an unencrypted HTTP connection, thereby preventing the cookie from being trivially intercepted by an attacker monitoring network traffic. If the secure flag is not set, then the cookie will be transmitted in clear-text if the user visits any HTTP URLs within the cookie's scope. An attacker may be able to induce this event by feeding a user suitable links, either directly or via another web site.
