Wekan is open source kanban built with Meteor. Prior to 9.32, Wekan OIDC-related Meteor methods in packages/wekan-oidc/oidc_server.js, server/models/org.js, and server/models/team.js are globally callable without the admin authorization checks used by their non-OIDC counterparts. Authenticated users can call setCreateOrgFromOidc, setOrgAllFieldsFromOidc, setCreateTeamFromOidc, setTeamAllFieldsFromOidc, boardRoutineOnLogin, or groupRoutineOnLogin to create or modify organizations and teams, and groupRoutineOnLogin can grant global admin privileges when PROPAGATE_OIDC_DATA is enabled.
This issue is fixed in version 9.32.
