CVE-2026-29059 Details
Description
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.
A path traversal vulnerability has been identified in Windmill versions prior to 1.603.3, specifically in the 'get_log_file' endpoint. The vulnerability allows unauthenticated users to read arbitrary files on the server by exploiting the 'filename' parameter, which is not properly sanitized and can be manipulated using '../' sequences. This issue has been addressed in version 1.603.3.
Users should upgrade to Windmill version 1.603.3 or later. Nextcloud Flows is transitioning to a new integration that decouples it from Windmill, allowing independent updates.
