CVE-2023-45816 Information

Description

Discourse is an open source platform for community discussion. Prior to version 3.1.3 of the stable branch and version 3.2.0.beta3 of the beta and tests-passed branches there is an edge case where a bookmark reminder is sent and an unread notification is generated but the underlying bookmarkable (e.g. post topic chat message) security has changed making it so the user can no longer access the underlying resource. As of version 3.1.3 of the stable branch and version 3.2.0.beta3 of the beta and tests-passed branches bookmark reminders are now no longer sent if the user does not have access to the underlying bookmarkable and also the unread bookmark notifications are always filtered by access. There are no known workarounds.
