From d4fc0d2c5afff4c13285b415b1a61ccf33d610cc Mon Sep 17 00:00:00 2001 From: Gergely Nagy Date: Thu, 7 Dec 2023 12:57:16 +0100 Subject: [PATCH] [GITEA] Allow changing the email address before activation During registration, one may be required to give their email address, to be verified and activated later. However, if one makes a mistake, a typo, they may end up with an account that cannot be activated due to having a wrong email address. They can still log in, but not change the email address, thus, no way to activate it without help from an administrator. To remedy this issue, lets allow changing the email address for logged in, but not activated users. This fixes gitea#17785.

See e7cb8da2a8 * Always enable caches (#28527) (cherry picked from commit 43ded8ee30ab5c7a40a456600cdaa8a0fbdccec2) Rate limit pre-activation email change separately Changing the email address before any email address is activated should be subject to a different rate limit than the normal activation email resending. If there's only one rate limit for both, then if a newly signed up quickly discovers they gave a wrong email address, they'd have to wait three minutes to change it. With the two separate limits, they don't - but they'll have to wait three minutes before they can change the email address again. The downside of this setup is that a malicious actor can alternate between resending and changing the email address (to something like `user+$idx@domain`, delivered to the same inbox) to effectively halving the rate limit. I do not think there's a better solution, and this feels like such a small attack surface that I'd deem it acceptable. The way the code works after this change is that `ActivatePost` will now check the `MailChangeLimit_user` key rather than `MailResendLimit_user`, and if we're within the limit, it will set `MailChangedJustNow_user`. The `Activate` method - which sends the activation email, whether it is a normal resend, or one following an email change - will check `MailChangedJustNow_user`, and if it is set, it will check the rate limit against `MailChangedLimit_user`, otherwise against `MailResendLimit_user`, and then will delete the `MailChangedJustNow_user` key from the cache. Fixes #2040.
