Overview
Affected versions of this package are vulnerable to Brute Force due to improper enforcement of authentication attempts in the validate_protected_action_otp function. An attacker can gain unauthorized access to protected actions, such as retrieving API keys or deleting accounts, by brute-forcing the one-time passcode without being limited by the intended rate limit.
