Vulnerability details
The vulnerability allows a remote attacker to hijack a user's authenticated session.
The vulnerability exists due to improper cookie security attribute configuration in JWTRefreshMiddleware when setting the JWT authentication cookie behind an https-terminating reverse proxy. A remote attacker can induce a logged-in user's browser to send a cleartext HTTP request and capture the JWT cookie to hijack a user's authenticated session.
Exploitation requires the deployment to be behind a TLS-terminating proxy and user interaction is required from a logged-in user.
