CVE-2024-24817

User can see invitees in events created in PMs and private categories

Published Feb 22, 2024 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed
Description
Discourse Calendar adds the ability to create a dynamic calendar in the first post of a topic on the open-source discussion platform Discourse. Prior to version 0.4, event invitees created in topics in private categories or PMs (private messages) can be retrieved by anyone, even if they're not logged in. This problem is resolved in version 0.4 of the discourse-calendar plugin. While no known workaround is available, putting the site behind `login_required` will disallow this endpoint to be used by anonymous users, but logged in users can still get the list of invitees in the private topics.
