Upgrade org.graylog2:graylog2-server to version 7.0.11, 7.1.6 or higher.
Overview
org.graylog2:graylog2-server is a log management platform.
Affected versions of this package are vulnerable to Missing Authorization via the duplicate handler in EventDefinitionsResource for the POST /events/definitions/{definitionId}/duplicate endpoint. An attacker can clone any event definition by sending a duplicate request for a target definitionId while holding only the general eventdefinitions:create permission. This lets an authenticated low-privilege user read private event definitions they are not allowed to access, exposing detection queries, aggregation thresholds, grouping fields, schedules, and notification bindings through the cloned definition.
