Technical details

The PATCH /api/v1/@apostrophecms/settings/password endpoint verifies the current password via verifyPassword() but bypasses the login module's failed-attempt counter, throttle, and lockout mechanisms. An authenticated attacker can submit unlimited password guesses at normal response speed (226–232 ms per attempt), whereas the login route enforces these protections. Successful guessing leads to password replacement and account takeover.
