    CVE-2026-31283

    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.
