Because Apple's InstallEnterpriseApplication MDM command requires these URLs to be reachable without a Fleet session, they cannot rely on session-based authentication, and the missing token allows an unauthenticated attacker with network access to the Fleet server to download in-house IPA binaries and their metadata (bundle identifier, version, and name) by guessing sequential title identifiers. The impact is limited to read-only disclosure; there is no privilege escalation or write access, and the free tier is unaffected (it returns fleet.ErrMissingLicense).","categories":["Libraries & packages"],"product":"fleet","vendor":"fleetdm","ecosystem":"Go","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101047","source_modified_at":"2026-09-30T14:47:15.528Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"fleet","vendor":"fleetdm","versions":[{"lessThan":"4.87.0","status":"affected","version":"0","versionType":"semver"},{"status":"unaffected","version":"4.87.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-q9c5-pp7m-fm2g","source_modified_at":"2026-09-28T03:55:37.116573482Z","fetched_at":"2026-10-23T18:55:00.935475Z","package":{"name":"github.com/fleetdm/fleet/v4","ecosystem":"Go","purl":"pkg:golang/github.com/fleetdm/fleet/v4"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.87.0"}]}],"versions":[]}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101047","source_modified_at":"2026-09-30T14:47:15.528Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"fleet","ecosystem":null},"version":"4.87.0","basis":"first unaffected version stated in the CVE record"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-q9c5-pp7m-fm2g","source_modified_at":"2026-09-28T03:55:37.116573482Z","fetched_at":"2026-10-23T18:55:00.935475Z","package":{"name":"github.com/fleetdm/fleet/v4","ecosystem":"Go","purl":"pkg:golang/github.com/fleetdm/fleet/v4"},"version":"4.87.0"}],"cvss":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00244,"percentile":0.14725,"score_date":"2026-10-23"},"published_at":"2026-09-27T17:02:35.852Z","modified_at":"2026-09-30T14:47:15.528Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-101047","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T14:47:15.528Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-q9c5-pp7m-fm2g","fetched_at":"2026-10-23T18:55:00.935475Z","source_modified_at":"2026-09-28T03:55:37.116573482Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-101047","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/fleetdm/fleet/security/advisories/GHSA-q9c5-pp7m-fm2g","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/fleet-before-4.87.0-unauthenticated-ios-app-download-via-predictable-urls","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-09-30T14:47:09.359033Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-30T14:47:15.528Z","content_hash":"3e1c936e80b2da5c554c7d6307b396c02fe23e165c163a1d572d5fd6b8907145"}}
