CVE-2023-45816

Summary

CVE-2023-45816 is a vulnerability affecting Discourse, an open-source platform for community discussion. The vulnerability was present in versions prior to 3.1.3 of the stable branch and versions 3.2.0.beta3 of the beta and tests-passed branches. It involved an edge case where a bookmark reminder was sent and an unread notification was generated, but the user could no longer access the underlying resource due to a change in security permissions. However, this issue has been resolved in version 3.1.3 of the stable branch and version 3.2.0.beta3 of the beta and tests-passed branches, where bookmark reminders are no longer sent if the user lacks access to the underlying bookmarkable resource, and unread bookmark notifications are always filtered by access. There are no known workarounds for this vulnerability. The potential danger it poses to an organization is considered low, with a base severity rating of LOW according to security advisories from GitHub.com.
