Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The use of deprecated token validation libraries created an authentication bypass risk in the middleware, which was resolved by migrating to a more robust validation framework.
Hardcoded Secret: A default hardcoded JWT signing secret was fallback-configured during deployment, leaving production environments vulnerable to predictable token signing.
Cryptographic Issues: Weak or default credentials could be silently accepted at startup without validation checks on the length or strength of the JWT signing key.
