The UDID is stored safely via parameterized queries, but is later interpolated directly into SQL when the async worker processes the job. This enables blind, boolean-based, and UNION-based SQL injection across four simultaneous subqueries.\n\nBecause Fleet's database driver is configured with `multiStatements=true`, the attacker can also execute stacked queries, enabling arbitrary writes to the database. This includes inserting new admin accounts, modifying configuration, deploying malicious profiles or scripts to managed devices, and deleting data.\n\nExploitation requires a valid SCEP-issued enrollment certificate (mTLS), but any enrolled device, including attacker-controlled devices, can exploit this vulnerability.\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.\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)](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-v895-833r-8c45" }, { "category": "other", "text": "0.00018", "title": "EPSS" }, { "category": "other", "text": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U", "title": "CVSSV4" }, { "category": "other", "text": "6.2", "title": "CVSSV4 base score" }, { "category": "other", "text": "3.9", "title": "NCSC Score" }, { "category": "other", "text": "There is product data available from source Certbundde", "title": "NCSC Score top increasing factors" }, { "category": "other", "text": "There is cwe data available from source Github, There is cwe data available from source Nvd, Is related to a product by vendor Open Source, Is related to (a version of) an uncommon product, The value of the most recent EPSS score, The value of the most recent CVSS (V3) score", "title": "NCSC Score top decreasing factors" } ], "product_status": { "known_affected": [ "CSAFPID-5944572", "CSAFPID-5963606" ] }, "references": [ { "category": "external", "summary": "Source - cveprojectv5", "url": "https://raw.githubusercontent.com/CVEProject/cvelistV5/main/cves/2026/34xxx/CVE-2026-34385.json" }, { "category": "external", "summary": "Source - nvd", "url": "https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-34385" }, { "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": "Source - github", "url": "https://api.github.com/advisories/GHSA-v895-833r-8c45" }, { "category": "external", "summary": "Reference - certbundde; cveprojectv5; github; nvd", "url": "https://github.com/fleetdm/fleet/security/advisories/GHSA-v895-833r-8c45" }, { "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-m2h6-4xpq-qw3m" }, { "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" }, { "category": "external", "summary": "Reference - github", "url": "https://nvd.nist.gov/vuln/detail/CVE-2026-34385" }, { "category": "external", "summary": "Reference - github", "url": "https://github.com/advisories/GHSA-v895-833r-8c45" } ], "title": "CVE-2026-34385" } ] }
