Severity CVSS v4.0:
LOW
Type:

Description

An authenticated user holding cursor termination privileges on one database may incorrectly be permitted to terminate active cursors on a separate database, disrupting ongoing query operations for other users. The behavior stems from an authorization check that does not correctly scope privileges to the appropriate namespace.
