The vulnerability requires administrator privileges to exploit. Two different CVSS vectors were assigned: NIST provided a score of 7.2 (HIGH) with vector CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, while Patchstack assigned a score of 7.6 (HIGH) with vector CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:L (NVD).

The vulnerability could allow a malicious actor with administrator privileges to directly interact with the database, potentially leading to unauthorized access to sensitive information. The severity is considered high, though the actual impact is mitigated by the requirement of administrator-level access (Patchstack).
