Summary

Decidim: JWT-backed authentication can be replayed across organizations

Details

Decidim is a participatory democracy framework. Prior to 0.31.5 and in 0.32.0.rc1 before 0.32.0.rc2, JWT-backed API authentication is not bound to the organization selected by the current host, allowing a JWT issued for one tenant to be replayed against another tenant’s API to read participantDetails data and reach the proposal.answer mutation path. This issue is fixed in versions 0.31.5 and 0.32.0.rc2.
