Vulnerability Details
Hey guys, When registered for an account, the confirmation email sent out, has a http link (refer the attachment) and allows a man-in-the-middle attacker to take over the account. He can do the following: - Obtain the confirmation tokens while transmitting to the weblate infra and redirect the user to a fake site. - On clicking the link, the user is auto logged in to the account. The attacker can take over the account if he obtains the tokens in the transmission. **Steps to reproduce:** - Navigate to https://hosted.weblate.org/accounts/register/ - Fill up the form and submit - Open the email inbox - See the link contains http://. Verify both the visible text as well as the actually link is http://. - Note that all other links are http:// too **Suggested Fix:** - Change the confirmation link sent through the email, to *https://*. Both the text visible as well as the actual link. - Avoid automatic logging into the account when the link is clicked. Display a message saying *Your account is verified. Please login to continue. **Affected area:** https://hosted.weblate.org/accounts/register/
