CVE-2026-0545

Name of the Vulnerable Software and Affected Versions mlflow/mlflow (affected versions not specified)

Description The FastAPI job endpoints under /ajax-api/3.0/jobs/* in mlflow/mlflow are not protected by authentication or authorization when the basic-auth app is enabled. If job execution is enabled (MLFLOW SERVER ENABLE JOB EXECUTION=true) and any job function is allowlisted, any network client can submit, read, search, and cancel jobs without credentials, bypassing basic-auth entirely. This can lead to unauthenticated remote code execution if allowed jobs perform privileged actions such as shell execution or filesystem changes. Even if jobs are deemed safe, this still constitutes an authentication bypass, potentially resulting in job spam, denial of service (DoS), or data exposure in job results.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
