CVE-2026-72542Network attack vectorHinoki check available

Cross-job data access via unchecked metrics handlers

Published Aug 11, 2026 · Updated Aug 11, 2026

Missing authorization in Windmill Labs Windmill through 1.783.0 allows remote authenticated users to read or alter any workspace job's metrics. The job_metrics handlers accept requests without an authorization extractor, so workspace ownership checks do not run for metric reads or progress writes. Operator access is sufficient to inspect sensitive execution data and inject misleading progress into jobs owned by others.
