How to fix?

Upgrade github.com/greenpau/caddy-security to version 1.0.42 or higher.

Overview

github.com/greenpau/caddy-security is a Security App and Plugin for Caddy v2.

Affected versions of this package are vulnerable to Insecure Randomness due to using an insecure random number generation library which could possibly be predicted via a brute-force search. Attackers could use the potentially predictable nonce value used for authentication purposes in the OAuth flow to conduct OAuth replay attacks. In addition, insecure randomness is used while generating multifactor authentication (MFA) secrets and creating API keys in the database package.
