Description

Currently, it is possible to retrieve valid e-mailaddreses from the system by simply trying to request a password for it. If the emailaddress is not valid, Redmine will show a notification stating this.

It would be better to have this form output a success message in every scenario in order to make e-mail harvesting harder.

I completely agree. Redmine should always display notice_account_lost_email_sent ("An email with instructions to choose a new password has been sent to you.").

Hello,

I comment on this 12 years old defect because this is the only active one I found regarding this subject.
Is there a version in which this issue has been addressed, or a workaround ?

Thanks.
Regards,
JL

The attached patch changes the message when the entered email address is invalid as follows. Comments are welcome.

Before: "Invalid user"
After: "An email with instructions to choose a new password has been sent to you"

This patch should indeed do the trick, thanks !

I would even suggest updating the message to more accurately reflect the reality. Something like "An email with instructions to choose a new password has been sent if the mail address matches an existing account"
