CVE-2026-72542
Windmill Labs Windmill - Missing Authorization
Description

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.

Solution
Implement authorization checks for job progress and metrics handlers to prevent unauthorized access.
  • Update Windmill Labs Windmill to a version later than 1.783.0.
  • Implement workspace-level access controls for job handlers.
  • Validate operator ownership before accessing job data.
  • Ensure authorization logic is applied to all job handlers.
