CVE-2024-32034 — decidim is a Free Open-Source participatory democracy, citizen participation and open government for cities and organizations

Medium CVSS 6.8

decidim is a Free Open-Source participatory democracy, citizen participation and open government for cities and organizations. The admin panel is subject to potential Cross-site scripting (XSS) attach in case an admin assigns a valuator to a proposal, or does any other action that generates an admin activity log where one of the resources has an XSS crafted. This issue has been addressed in release version 0.27.7, 0.28.2, and newer. Users are advised to upgrade. Users unable to upgrade may redirect the pages /admin and /admin/logs to other admin pages to prevent this access (i.e. `/admin/organization/edit`).

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
