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

Description The issue concerns excessive directory permissions in MLflow, which can lead to local privilege escalation when using spark udf. This behavior can be exploited by a local attacker to gain elevated permissions by using a Time-of-Check-to-Time-of-Use (ToCToU) attack. The issue is only relevant when the spark udf() MLflow API is called.

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