Description
Decidim is a participatory democracy framework. Prior to 0.30.9, from 0.31.0 before 0.31.5, and in 0.32.0.rc1 before 0.32.0.rc2, the identity-document verification admin controllers load pending Authorization records by raw identifier without confirming current_organization ownership, allowing an administrator from one tenant to view, approve, or reject another tenant’s ID-document request. This issue is fixed in versions 0.30.9, 0.31.5, and 0.32.0.rc2.
