CVE-2022-46177 Information

Description

Discourse is an option source discussion platform. Prior to version 2.8.14 on the stable branch and version 3.0.0.beta16 on the beta and tests-passed branches when a user requests for a password reset link email then changes their primary email the old reset email is still valid. When the old reset email is used to reset the password the Discourse account’s primary email would be re-linked to the old email. If the old email address is compromised or has transferred ownership this leads to an account takeover. This is however mitigated by the SiteSetting email_token_valid_hours which is currently 48 hours. Users should upgrade to versions 2.8.14 or 3.0.0.beta15 to receive a patch. As a workaround lower email_token_valid_hours as needed.
