CVE-2024-41673Network attack vector

Script execution via unescaped version URL

Published Oct 1, 2024 · Updated Oct 1, 2024

Cross-site scripting in Decidim before 0.27.8 allows remote attackers to execute scripts in a user's browser through a malformed version URL. Version views pass the URL id parameter directly as the version cell index and render its translated output without HTML escaping. Exploitation requires a user to open the crafted URL and can expose browser-accessible data or alter displayed content.
