{"id":"CVE-2026-101047","state":"PUBLISHED","title":"Fleet before 4.87.0 Unauthenticated iOS App Download via Predictable URLs","description":"Fleet before 4.87.0 does not protect the two endpoints that serve in-house iOS application packages and manifests (enterprise tier only) with the intended random, time-limited URL token. 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).","publishedAt":"2026-09-27T17:02:35.852Z","updatedAt":"2026-09-30T14:47:15.528Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["fleetdm fleet"],"affected":[{"vendor":"fleetdm","product":"fleet","packageURL":"pkg:golang/github.com/fleetdm/fleet/v4","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"4.87.0","versionType":"semver"},{"version":"4.87.0","status":"unaffected","versionType":"semver"}]}],"references":["https://github.com/fleetdm/fleet/security/advisories/GHSA-q9c5-pp7m-fm2g","https://www.vulncheck.com/advisories/fleet-before-4.87.0-unauthenticated-ios-app-download-via-predictable-urls"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/101xxx/CVE-2026-101047.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-101047","state":"PUBLISHED","datePublished":"2026-09-27T17:02:35.852Z","dateUpdated":"2026-09-30T14:47:15.528Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-09-27T15:48:49.472Z"},"containers":{"cna":{"title":"Fleet before 4.87.0 Unauthenticated iOS App Download via Predictable URLs","descriptions":[{"lang":"en","value":"Fleet before 4.87.0 does not protect the two endpoints that serve in-house iOS application packages and manifests (enterprise tier only) with the intended random, time-limited URL token.
