Flask-AppBuilder Has No Rate Limiting on Login AUTH DB
### Impact Lack of rate limiting will allow an attacker to brute-force user credentials. ### Patches Ability to enable rate limiting on Flask-AppBuilder >= 4.3.0. Use `AUTH_RATE_LIMITED = True` and `RATELIMIT_ENABLED = True` set the limit itself by using `AUTH_RATE_LIMIT`. Will apply only to database authentication. ### Workarounds Implement rate limiting using a reverse proxy or other strategies.
