Description

Windmill is an open-source developer platform for internal code: APIs, background jobs, workflows and UIs.

The filename parameter is concatenated into a file path without sanitization, allowing an attacker to read arbitrary files on the server using ../ sequences. This issue has been patched in version 1.603.3.
