• Maven org.graylog2:graylog2-server: >= 6.3.0, < 6.3.14 → fixed in 6.3.14 • Maven org.graylog2:graylog2-server: >= 7.0.0, < 7.0.9 → fixed in 7.0.9 • Maven org.graylog2:graylog2-server: >= 7.1.0, < 7.1.4 → fixed in 7.1.4

Impact A vulnerability was found in Graylog's API endpoint for updating saved searches and dashboards. A user with edit permissions on a dashboard or saved search could grant owner permissions to an arbitrary account, which could then be used to delete the respective saved search or dashboard or to remove the original owner's access. Patches This issue has been patched in the following Graylog versions: `6.3.14`, `7.0.9`, `7.1.4`. Affected users should upgrade to one of these versions or above to remediate the vulnerability. Graylog Cloud has already been patched. Workaround There is no known workaround. Upgrading to a patched version is recommended. Credits Thanks to Jan Kahmen, turingpoint for reporting.
