Description

Padloc 4.0.0 before 4.3.1 contains an authentication bypass vulnerability in the legacy retrieveMFAToken handler that never counts wrong email verification codes toward the attempt limit. Unauthenticated attackers knowing a victim's email can brute force the 6-digit code to obtain verification tokens usable in signup, login and account recovery flows.
