Insufficient server-side input validation allows crafted input to manipulate database queries in unintended ways.\n\nSuccessful exploitation could enable cross-team data corruption, exfiltration of sensitive information such as password hashes and API tokens, and potential privilege escalation. Exploitation requires authentication with team or global admin privileges and MDM to be enabled.\n\nThis issue does not affect instances where Apple MDM is disabled.\n\n### Workarounds\n\nIf an immediate upgrade is not possible, affected Fleet users should temporarily disable Apple MDM or limit admin roles.\n\n### For more information\n\nIf there are any questions or comments about this advisory:\n\nSend an email to  [security@fleetdm.com](mailto:security@fleetdm.com)\n\nJoin #fleet in [osquery Slack](https://join.slack.com/t/osquery/shared_invite/zt-h29zm0gk-s2DBtGUTW4CFel0f0IjTEw)\n\n### Credits\n\nFleet thanks the Secfox Research Team (@secfox-ai) for responsibly reporting this issue.","state":0,"publishedAt":"2026-03-30T19:18:29+00:00","modifiedAt":"2026-04-02T21:26:03.9410136+00:00","affected":[{"ecosystem":"Go","name":"github.com/fleetdm/fleet/v4","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"4.81.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/fleetdm/fleet/security/advisories/GHSA-9p23-p2m4-2r4m","https://nvd.nist.gov/vuln/detail/CVE-2026-34386","https://github.com/fleetdm/fleet"],"sourceUrl":"https://github.com/advisories/GHSA-9p23-p2m4-2r4m","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-9p23-p2m4-2r4m","identifiers":["GHSA-9p23-p2m4-2r4m","CVE-2026-34386","GO-2026-4913"]},"retained":false,"historicalAffected":[]},{"revision":"d82ff12bf2d34cf490e3ff3ec279333b","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-4913","aliases":["CVE-2026-34386","GHSA-9p23-p2m4-2r4m"],"title":"Fleet vulnerable to SQL Injection in MDM bootstrap package by authenticated team or global admin in github.com/fleetdm/fleet","description":"Fleet vulnerable to SQL Injection in MDM bootstrap package by authenticated team or global admin in github.com/fleetdm/fleet","state":0,"publishedAt":"2026-04-02T18:42:30+00:00","modifiedAt":"2026-04-02T21:20:08.639838+00:00","affected":[{"ecosystem":"Go","name":"github.com/fleetdm/fleet/v4","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"4.81.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/fleetdm/fleet/security/advisories/GHSA-9p23-p2m4-2r4m","https://nvd.nist.gov/vuln/detail/CVE-2026-34386"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-4913","license":"OSV · upstream source license applies","key":"osv:GO-2026-4913","identifiers":["GO-2026-4913","CVE-2026-34386","GHSA-9p23-p2m4-2r4m"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
