Technical details
CTFd v3.7.6 is vulnerable to a man-in-the-middle (MITM) attack, allowing an attacker positioned on the network to intercept communications between clients and the server. The vulnerability likely stems from insufficient encryption, missing or improper HTTPS/TLS enforcement, or improper certificate validation. An attacker on the network path (adjacent network position or compromised intermediate network device) can intercept, read, and modify traffic without requiring authentication. This could allow attackers to steal session tokens, modify challenge submissions, or redirect users to malicious servers. Patched versions should be available from CTFd's repository.
