CVE-2024-24817 – User can see invitees in events created in PMs and private categories
https://notcve.org/view.php?id=CVE-2024-24817
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. Discourse Calendar agrega la capacidad de crear un calendario dinámico en la primera publicación de un tema en la plataforma de discusión de código abierto Discourse. • https://github.com/discourse/discourse-calendar/commit/84ef46a38cf02748ecacad16c5d9c6fec12dc8da https://github.com/discourse/discourse-calendar/security/advisories/GHSA-wwq5-g5cp-c69f • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2023-43658 – Improper escaping of user input in discourse-calendar
https://notcve.org/view.php?id=CVE-2023-43658
dicourse-calendar is a plugin for the Discourse messaging platform which adds the ability to create a dynamic calendar in the first post of a topic. Improper escaping of event titles could lead to Cross-site Scripting (XSS) within the 'email preview' UI when a site has CSP disabled. Having CSP disabled is a non-default configuration, so the vast majority of sites are unaffected. This problem is resolved in the latest version of the discourse-calendar plugin. Users are advised to upgrade. • https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP https://github.com/discourse/discourse-calendar/commit/9788310906febb36822d6823d14f1059c39644de https://github.com/discourse/discourse-calendar/security/advisories/GHSA-3fwj-f6ww-7hr6 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
