Résumé

Discourse Allows Unauthorized Access to Deleted Posts Index via Group Membership

Description d'origine

La description telle que publiée par la source (souvent en anglais).

Discourse is an open-source discussion platform. Prior to versions 2026.3.0, 2026.2.1, and 2026.1.2, a non-staff user with elevated group membership could access deleted posts belonging to any user due to an overly broad authorization check on the deleted posts index endpoint. Versions 2026.3.0, 2026.2.1, and 2026.1.2 contain a patch. No known workarounds are available.
