CVE-2026-45414 Details
Description
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.
A vulnerability in Decidim's JWT-backed API authentication prior to versions 0.31.5 and 0.32.0.rc2 allows tokens issued for one organization to be reused on another organization's API. This flaw enables access to sensitive data, such as participant details and the ability to answer proposals, by exploiting the trust boundary between organizations.
Users can update to Decidim versions 0.31.5 or 0.32.0.rc2, both of which include the necessary fix. Instructions for updating can be found in the release notes for these versions.
