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."}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')","cweId":"CWE-89","type":"CWE"}]}],"affected":[{"vendor":"fleetdm","product":"fleet","defaultStatus":"unaffected","packageURL":"pkg:golang/github.com/fleetdm/fleet/v4","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"4.89.0"},{"version":"4.89.0","status":"unaffected","versionType":"semver"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:fleetdm:fleet:*:*:*:*:*:*:*:*","versionEndExcluding":"4.89.0"}]}]}],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","vectorString":"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","attackVector":"NETWORK","attackComplexity":"HIGH","attackRequirements":"PRESENT","privilegesRequired":"LOW","userInteraction":"NONE","vulnConfidentialityImpact":"LOW","vulnIntegrityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","baseScore":2.3,"baseSeverity":"LOW"}},{"format":"CVSS","cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE","baseScore":3.1,"baseSeverity":"LOW"}}],"references":[{"url":"https://github.com/fleetdm/fleet/security/advisories/GHSA-rxhg-vcww-2mpw","tags":["vendor-advisory"],"name":"GitHub Security Advisory (GHSA-rxhg-vcww-2mpw)"},{"name":"VulnCheck Advisory: Fleet before 4.89.0 SQL Injection via ORDER BY Activity Endpoints","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/fleet-before-4.89.0-sql-injection-via-order-by-activity-endpoints"}],"credits":[{"lang":"en","value":"axel-corsiez","type":"reporter"}],"x_generator":{"engine":"vulncheck-endgame"}}}}
