Nim is vulnerable to man-in-the-middle attack. The vulnerability exists when during ‘nimble refresh’, the system fetches a list of Nimble packages over HTTPS without verifying the SSL/TLS certificate, allowing an attacker to perform man-in-the-middle attack by delivering a modified malicious package instead.
