Summary
Graylog is a free and open log management platform. From 6.3.0 until 6.3.14, 7.0.9, and 7.1.4, the view update API for saved searches and dashboards permits a user with edit permission but without entity ownership to include a shareRequest that grants owner permissions to an arbitrary account. The selected account can then delete the saved search or dashboard or remove the original owner's access. Graylog Cloud was patched before the advisory was published. This issue is fixed in versions 6.3.14, 7.0.9, and 7.1.4.
