Apache Kyuubi versions 1.6.0 through 1.11.9 are vulnerable due to an incomplete security fix that allows clients to bypass server-side configuration restrictions related to session directory access. This vulnerability could lead to unauthorized access and manipulation of session data, posing a significant risk to data integrity and confidentiality. Organizations using affected versions should prioritize upgrading to version 1.12.0 to mitigate this high-severity risk.
