What it is

🔥 A surprising lapse in permission checks means any logged-in user can manipulate survey templates in Decidim's admin panel! Think of it like a restaurant that lets any customer walk into the kitchen and change the menu items without asking — tasty for some, but chaos for everyone else! 🍽️ If exploited, an attacker could change, create, or even delete critical survey templates, completely undermining the integrity of participatory decision-making. This could lead to misinformation spreading like wildfire and trust in the system plummeting. Absolutely devastating for any organization relying on accurate feedback!

Put simply

Think of it like a restaurant that lets any customer walk into the kitchen and change the menu items without asking — tasty for some, but chaos for everyone else! 🍽️ This vulnerability arises from the `templates` module failing to enforce proper permission checks, allowing unauthorized access to administrative functions for logged-in users.

What to do

If exploited, an attacker could change, create, or even delete critical survey templates, completely undermining the integrity of participatory decision-making. This could lead to misinformation spreading like wildfire and trust in the system plummeting. Absolutely devastating for any organization relying on accurate feedback! Immediately update Decidim to versions 0.26.8 or 0.27.4 to patch this critical flaw. Assess your user access levels to ensure only trusted individuals can make changes to templates.
