{"id":"CVE-2026-101046","state":"PUBLISHED","title":"Fleet before 4.89.0 SQL Injection via ORDER BY Activity Endpoints","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.","publishedAt":"2026-09-27T17:02:35.154Z","updatedAt":"2026-09-28T13:16:02.557Z","severity":{"score":2.3,"label":"Low","version":"4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["fleetdm fleet"],"affected":[{"vendor":"fleetdm","product":"fleet","packageURL":"pkg:golang/github.com/fleetdm/fleet/v4","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"4.89.0","versionType":"semver"},{"version":"4.89.0","status":"unaffected","versionType":"semver"}]}],"references":["https://github.com/fleetdm/fleet/security/advisories/GHSA-rxhg-vcww-2mpw","https://www.vulncheck.com/advisories/fleet-before-4.89.0-sql-injection-via-order-by-activity-endpoints"],"weaknesses":["CWE-89"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/101xxx/CVE-2026-101046.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-101046","state":"PUBLISHED","datePublished":"2026-09-27T17:02:35.154Z","dateUpdated":"2026-09-28T13:16:02.557Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-09-27T15:48:49.472Z"},"containers":{"cna":{"title":"Fleet before 4.89.0 SQL Injection via ORDER BY Activity Endpoints","descriptions":[{"lang":"en","value":"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).
