Official description

In Sorcery before 0.15.0, there is a brute force vulnerability when using password authentication via Sorcery. The brute force protection submodule will prevent a brute force attack for the defined lockout period, but once expired, protection will not be re-enabled until a user or malicious actor logs in successfully. This does not affect users that do not use the built-in brute force protection submodule, nor users that use permanent account lockout. This has been patched in 0.15.0.
