⚠️ An unauthenticated user can execute arbitrary SQL commands in Nextcloud's Lookup Server, and it’s easier than you think! 🔥 Think of it like a restaurant where anyone can walk in and rewrite the menu without any checks. If they decide to swap out the chef's special for a mystery dish, chaos ensues! With this SQL injection vulnerability, an attacker could manipulate the database to retrieve or modify sensitive information, potentially leading to unauthorized access to user data or even complete system compromise. The possibilities are surprisingly sneaky and could have devastating consequences.
