Server-side JavaScript execution via currentItem evaluation
Published Sep 5, 2022 · Updated Aug 3, 2024
Server-side JavaScript injection in Appsmith 1.7.14 and earlier allows remote authenticated users to execute code through a List widget. When untrusted data is bound to a List, currentItem evaluates a crafted string as JavaScript instead of treating it as data. A victim must trigger currentItem in the affected application; injected code can hang the application or send Appsmith store data to an attacker-controlled server.
