Fleet's legacy MDM installer path mitigates this by embedding a random, hard-to-guess token in the URL; the in-house iOS app endpoints (added later) were always intended to use the same time-limited-token pattern but the mitigation was not yet in place.\n\nThe result is read-only disclosure of in-house IPA binaries and their metadata (bundle identifier, version, name) that an operator has deployed through Fleet. This is enterprise-tier only — the free tier returns `fleet.ErrMissingLicense`. There is no privilege escalation, write access, or impact on hosts not managed by Fleet.\n\n### Workarounds\n\nIf an immediate upgrade is not possible:\n\n- Restrict network access to the Fleet server to trusted networks, as is typical for MDM deployments.\n- Remove in-house iOS apps that contain sensitive material from Fleet; in-house app IPAs are intentionally reachable by managed devices and should not be relied on as a confidential distribution channel.\n- Where available, configure CloudFront URL signing for software installers to limit the validity window of issued binary URLs.\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\nEmail us 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\nWe thank @offset for responsibly reporting this issue.","state":0,"publishedAt":"2026-08-20T18:44:31+00:00","modifiedAt":"2026-09-28T03:55:37.1165735+00:00","affected":[{"ecosystem":"Go","name":"github.com/fleetdm/fleet/v4","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"4.87.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/fleetdm/fleet/security/advisories/GHSA-q9c5-pp7m-fm2g","https://github.com/fleetdm/fleet","https://github.com/fleetdm/fleet/releases/tag/fleet-v4.87.0"],"sourceUrl":"https://github.com/advisories/GHSA-q9c5-pp7m-fm2g","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-q9c5-pp7m-fm2g","identifiers":["GHSA-q9c5-pp7m-fm2g","CVE-2026-101047","GO-2026-6268"]},"retained":false,"historicalAffected":[]},{"revision":"5f045bf2734a49bc9066367e0b2b21f3","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-6268","aliases":["CVE-2026-101047","GHSA-q9c5-pp7m-fm2g"],"title":"Fleet: Unauthenticated download of in-house iOS app binaries via predictable URLs in github.com/fleetdm/fleet","description":"Fleet: Unauthenticated download of in-house iOS app binaries via predictable URLs in github.com/fleetdm/fleet","state":0,"publishedAt":"2026-08-25T15:00:02+00:00","modifiedAt":"2026-09-28T03:55:37.1165735+00:00","affected":[{"ecosystem":"Go","name":"github.com/fleetdm/fleet/v4","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"4.87.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/fleetdm/fleet/security/advisories/GHSA-q9c5-pp7m-fm2g","https://github.com/fleetdm/fleet/releases/tag/fleet-v4.87.0"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-6268","license":"OSV · upstream source license applies","key":"osv:GO-2026-6268","identifiers":["GO-2026-6268","CVE-2026-101047","GHSA-q9c5-pp7m-fm2g"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
