{"id":"CVE-2026-101046","published":"2026-09-27T18:16:31.037","lastModified":"2026-09-28T14:17:12.473","description":"Fleet before 4.89.0 contains an SQL injection vulnerability in the activity list endpoints (GET /api/v1/fleet/activities and GET /api/v1/fleet/hosts/{id}/activities). The deprecated cursor-pagination helper appendListOptionsWithCursorToSQL interpolated the caller-supplied sort/order key into the SQL ORDER BY clause without an allowlist, so an authenticated user with read access to Activity could order results by arbitrary columns. The impact is read-only and bounded to columns on the activity_past table that are not otherwise returned in these responses (e.g. details), allowing their values to be inferred through the resulting sort order; there is no write access, privilege escalation, or reachability of node_key or other host-join columns through these endpoints. Fixed in 4.89.0, which removes the deprecated helper and passes the sort column through SanitizeColumn.","cvssScore":3.1,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-89"],"vendors":[],"products":[],"references":[{"url":"https://github.com/fleetdm/fleet/security/advisories/GHSA-rxhg-vcww-2mpw","tags":[]},{"url":"https://www.vulncheck.com/advisories/fleet-before-4.89.0-sql-injection-via-order-by-activity-endpoints","tags":[]}],"exploitRefs":[{"url":"https://github.com/fleetdm/fleet/security/advisories/GHSA-rxhg-vcww-2mpw","tags":[]}],"hasPoc":true,"ai":null}
