Once transferred, the attacker gains full control over the stolen hosts, including the ability to execute scripts with root privileges.\n\n### Impact\n\nThe host transfer endpoints verify that the caller has write permission to the destination team but do not check whether the caller has any permission over the source team of the hosts being transferred.\n\nOnce hosts are transferred, the attacker's team MDM configuration is automatically applied to the stolen devices, and the attacker can execute scripts on them with root privileges. In multi-tenant Fleet deployments where teams represent business units, departments, or customers, this breaks all team isolation guarantees. A bulk transfer variant allows stealing all matching hosts fleet-wide in a single request.\n\nExploitation requires authentication as a team maintainer or team admin.\n\n### Workarounds\n\nThere is no workaround for this issue short of upgrading to a patched version. Organizations concerned about exploitation should audit host transfer activity in their Fleet logs for any unexpected team reassignments.\n\n### For more information\n\nIf there are any questions or comments about this advisory:\n\nEmail Fleet at [security@fleetdm.com](mailto:security@fleetdm.com)\nJoin #fleet in [osquery Slack](https://join.slack.com/t/osquery/shared_invite/zt-h29zm0gk-s2DBtGUTW4CFel0f0IjTEw)\n\n### Credits\n\nFleet thanks @secfox-ai for responsibly reporting this issue.", "title": "github - https://api.github.com/advisories/GHSA-m2h6-4xpq-qw3m" }, { "category": "other", "text": "0.00038", "title": "EPSS" }, { "category": "other", "text": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U", "title": "CVSSV4" }, { "category": "other", "text": "4.9", "title": "CVSSV4 base score" }, { "category": "other", "text": "4.5", "title": "NCSC Score" }, { "category": "other", "text": "There is product data available from source Certbundde", "title": "NCSC Score top increasing factors" }, { "category": "other", "text": "Is related to (a version of) an uncommon product, Is related to a product by vendor Open Source", "title": "NCSC Score top decreasing factors" } ], "product_status": { "known_affected": [ "CSAFPID-5944573", "CSAFPID-5963606" ] }, "references": [ { "category": "external", "summary": "Source - cveprojectv5", "url": "https://raw.githubusercontent.com/CVEProject/cvelistV5/main/cves/2026/29xxx/CVE-2026-29180.json" }, { "category": "external", "summary": "Source - nvd", "url": "https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-29180" }, { "category": "external", "summary": "Source - github", "url": "https://api.github.com/advisories/GHSA-m2h6-4xpq-qw3m" }, { "category": "external", "summary": "Source - first", "url": "https://api.first.org/data/v1/epss?limit=10000&offset=0" }, { "category": "external", "summary": "Source - certbundde", "url": "https://wid.cert-bund.de/.well-known/csaf/white/2026/wid-sec-w-2026-0902.json" }, { "category": "external", "summary": "Reference - certbundde; cveprojectv5; github; nvd", "url": "https://github.com/fleetdm/fleet/security/advisories/GHSA-m2h6-4xpq-qw3m" }, { "category": "external", "summary": "Reference - github", "url": "https://github.com/fleetdm/fleet/releases/tag/fleet-v4.81.1" }, { "category": "external", "summary": "Reference - github", "url": "https://github.com/advisories/GHSA-m2h6-4xpq-qw3m" }, { "category": "external", "summary": "Reference - github", "url": "https://nvd.nist.gov/vuln/detail/CVE-2026-29180" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://wid.cert-bund.de/.well-known/csaf/white/2026/wid-sec-w-2026-0902.json" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://wid.cert-bund.de/portal/wid/securityadvisory?name=WID-SEC-2026-0902" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://github.com/fleetdm/fleet/security/advisories/" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://github.com/fleetdm/fleet/security/advisories/GHSA-3458-r943-hmx4" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://github.com/fleetdm/fleet/security/advisories/GHSA-4f9r-x588-pp2h" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://github.com/fleetdm/fleet/security/advisories/GHSA-7rhw-5mpv-gp4h" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://github.com/fleetdm/fleet/security/advisories/GHSA-99hj-44vg-hfcp" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://github.com/fleetdm/fleet/security/advisories/GHSA-9p23-p2m4-2r4m" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://github.com/fleetdm/fleet/security/advisories/GHSA-v895-833r-8c45" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://github.com/fleetdm/fleet/security/advisories/GHSA-w254-4hp5-7cvv" }, { "category": "external", "summary": "Reference - certbundde", "url": "https://github.com/fleetdm/fleet/security/advisories/GHSA-wg7j-pcc3-h4rh" } ], "scores": [ { "cvss_v3": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.8, "baseSeverity": "HIGH" }, "products": [ "CSAFPID-5944573", "CSAFPID-5963606" ] } ], "title": "CVE-2026-29180" } ] }
