CVE-2026-45330 · Severity: medium · CVSS 4.9 · Published 2026-07-31

Decidim, a participatory democracy framework, contains a security flaw in its identity verification system. In multi-tenant environments, an administrator from one organization can view, approve, or reject identity document requests belonging to a different organization. This could lead to the unauthorized exposure of sensitive personal identification documents and compromise the integrity of the verification process across different groups using the same platform.

## Technical details

A broken access control vulnerability exists in Decidim's identity-document verification admin controllers. The software loads pending Authorization records using raw identifiers without verifying that the record belongs to the 'current_organization' of the logged-in administrator. This allows a high-privileged user (administrator) from one tenant to perform Insecure Direct Object Reference (IDOR) attacks to view, approve, or reject ID-document requests from other tenants. The issue is rooted in missing authorization checks (CWE-862) and authorization bypass through user-controlled keys (CWE-639). Patches are available in versions 0.30.9, 0.31.5, and 0.32.0.rc2.
