CVE-2026-29059
Confirmed PUBLISHEDWindmill: SUPERADMIN_SECRET (rarely used) can be accessed publicly
Not yet in CISA KEV
Recommended Action
Prioritize immediate patching and validate internet-facing exposure. Monitor for matching exploitation attempts in your environment.
At a Glance
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.

Recommended Actions
- Prioritize immediate patching and validate internet-facing exposure. Monitor for matching exploitation attempts in your environment.
- Review sensor telemetry for request paths, attacker IPs, and payload patterns that may inform detection and exposure validation.
- Check enrichment artifacts for scanner coverage and available PoCs before rolling remediation validation.
- Use the Pro API to automate enrichment, telemetry, and workflow delivery for VM, SOC, and CTI pipelines.
