Summary
Windmill is an open-source developer platform for internal code: APIs, background jobs, workflows and UIs. Workspace environment variable values are interpolated into JavaScript string literals without escaping single quotes in the NativeTS executor. A workspace admin who sets a custom environment variable with a value containing ' can inject arbitrary JavaScript that executes inside every NativeTS script in that workspace. This is a code injection bug in worker.rs, not related to the sandbox/NSJAIL topic. Version 1.664.0 patches the issue.
