Overview
Affected versions of this package are vulnerable to Missing Authentication for Critical Function via the FastAPI endpoints under /ajax-api/3.0/jobs/* when the basic-auth app is enabled. An attacker can gain unauthorized access to submit, read, search, and cancel jobs by sending network requests without credentials, potentially leading to remote code execution, data exposure, or denial of service.
Note:
This is only exploitable if job execution is enabled (MLFLOW_SERVER_ENABLE_JOB_EXECUTION=true) and at least one job function is allowlisted.
