Official description

Decidim is a participatory democracy framework. Prior to 0.32.0, a low-privilege process-scoped administrator or election editor with question-management rights can store HTML or script-bearing content in question.body. The question_title helper returns the translatable question body through html_safe without a sanitization boundary, causing stored script execution when visitors open public election pages or voting booth screens. The persisted script executes in visitors' browsers. The vulnerability is fixed in 0.32.0.
