In Totara LMS v19.1.5 and before, the forgot password API does not implement rate limiting for the target email address. which can be used for an Email Bombing attack. NOTE: the Supplier's position is that the pwresettime configuration defaults to 30 minutes, the pwresettime configuration is a hard control enforced via flag PWRESET_STATUS_ALREADYSENT, and no further password-reset email messages are sent if this flag is active for a specific email address.
