CVE-2026-72542 (GCVE-0-2026-72542)

Vulnerability from cvelistv5 – Published: 2026-08-11 11:08 – Updated: 2026-08-11 12:33

Title

Windmill Labs Windmill - Missing Authorization

Summary

A missing authorization vulnerability in Windmill Labs Windmill through 1.783.0 allows authenticated operators to write job progress and read job metrics for any job in the workspace regardless of ownership. The job_metrics handlers accept no authorization extractor, bypassing workspace-level access controls. An operator can monitor sensitive job execution data and inject misleading progress for jobs they do not own.

Severity

5.4 (Medium)
