What the vulnerability does

01Description

Windmill is an open-source developer platform for internal code: APIs, background jobs, workflows and UIs. Prior to version 1.603.3, an unauthenticated path traversal vulnerability exists in Windmill's get_log_file endpoint "(/api/w/{workspace}/jobs_u/get_log_file/{filename})". 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.
