🚨 A sneaky Server-Side Template Injection in Form.io could lead to Remote Code Execution just by touching the default Email template URL. 🔥 Imagine a restaurant where the chef can whip up any dish just by reading a menu—no checks, just straight to the kitchen! This SSTI lets an admin do exactly that, executing malicious code while deleting the email template. If exploited, an attacker could execute arbitrary code on the server, effectively giving them the keys to the entire kitchen. This means they could change settings, access sensitive data, or even wipe important files, leading to devastating consequences for your application and users.
