#42957 new defect (bug)

Usernames ending in a period generate invalid reset password links in certain email clients

Description

Password reset links contain the username appended to the end of the URL. If the user name ends in a period the email client has to decide if the period is part of the URL or part of the punctuation of the sentence. For example:

<https://some-wordpress-site.com/wp-login.php?action=rp&key=V4LSmgBcwtqvFPEiFt0e&login=p.o.>

Gmail generates a clickable link that stops short of the final period. Outlook successfully links the entire URL.

Periods are valid in URLs, but we can avoid the issue by forcing "." to encode to "%2E" when generating the link in the email. PHP automatically converts the "%2E" back to "." when it's passed into the receiving side.

It looks like this type of email can be sent out in 2 scenarios that I can find.

  1. New user email with a link to access their account
  2. Password reset.

I can confirm that both are broken for me in GMail, too. When clicking the link in GMail I get invalid token. I tested with the thick Outlook client and outlook.com webmail and both of those worked fine. Seems isolated to GMail. Given how many people use gmail this seems like a good one to fix.

Your initial patch fixed the Reset Password process with a test user.

Could you update the patch for the new user email process as well?

It would be great to fix this bug, which I discovered as the source of pain for my users for years (and me, since I usually have to do a manual reset for them).

I see it's been dormant for a while, but I also see the fix. How can I help this fix go in?

On my website we get about one email a month from a person who can't create an account. This turns out to be caused by https://core.trac.wordpress.org/ticket/42957

  • you're using gmail
  • you try to create an account name ending in a period, e.g. Dave P.
  • the email is sent containing https://blah...&login=Dave%20P.
  • gmail generally assumes links ending in periods have the periods added by humans and thus ignores them
  • so clicking on it, you arrive at https://blah...&login=Dave%20P and the user's told the link is invalid

Fixes this by encoding the trailing period as an entity.

This is my first submitted pull request to WP, thanks in advance for telling me if any more steps are needed.
