Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Fleet (github.com/fleetdm/fleet/v4) versions before 4.89.0 are vulnerable to SQL ORDER BY column injection on the activity list endpoints. An authenticated user with read access to Activity can sort by columns not otherwise returned in the responses, though the source says this is read-only and does not reach host-join columns such as node_key. Upgrade to Fleet 4.89.0 or later.
