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 /admin/csv_census/census_logs record-management endpoints do not enforce full administrator authorization before rendering or mutating Decidim::Verifications::CsvDatum, allowing a participant manager to create, alter, or remove census records. This issue is fixed in versions 0.30.9, 0.31.5, and 0.32.0.rc2.

GHSA-q79h-67vx-m9xg — Decidim: CSV census record endpoints improper authorization

Affected: RubyGems: decidim-verifications

## Description

A participant manager can access and modify the CSV census record admin forms.

## Technical description

The CSV census admin record-management surface under `/admin/csv_census/census_logs` does not enforce admin-only authorization before rendering or mutating `Decidim::Verifications::CsvDatum`.

A participant manager (which can only manage participants) can therefore open the admin forms, create or update census rows, and delete rows directly.

Reproduction steps: 1. Sign in a participant admin and open `http://localhost:3000/admin/csv_census/census_logs/new_record` in the browser. Confirm the create form loads even though the session is not a full admin.

Note that normal participant accounts were not able to access the CSV census records which is good.

### Impact Any participant admin can create, alter, or remove CSV census rows, which can corrupt verification data relied on by authorization workflows.

### Patches

See https://github.com/decidim/decidim/pull/16674 and https://github.com/decidim/decidim/pull/16703

### Workarounds
