Technical details

A vulnerability classified as CWE-280 (Improper Handling of Insufficient Permissions or Privileges) exists in Apache Kvrocks versions 2.8.0 through 2.15.0. The flaw allows an authenticated user with low privileges to bypass intended access controls due to improper validation of permissions. Exploitation requires network connectivity and minimal user interaction, potentially resulting in a full compromise of the database's confidentiality, integrity, and availability (VC:H/VI:H/VA:H). The issue is resolved in Apache Kvrocks version 2.16.0.
