HTTPOnly attribute is not set for session cookies in the application.

🕵️‍♂️ Proof of Concept

Cookie Without HTTPOnly Attribute

💥 Impact

When a cookie doesn’t have an HttpOnly flag, it can be accessed through JavaScript, which means that an XSS could lead to cookies being stolen. These include session cookies that can make it easier to achieve account/session takeover.
