CVE-2026-29059 (GCVE-0-2026-29059)
Vulnerability from cvelistv5 – Published: 2026-03-06 07:11 – Updated: 2026-04-07 13:16Title
Windmill: SUPERADMIN_SECRET (rarely used) can be accessed publicly
Summary
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.
