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).\n\n## Affected\n\n- `fleet < 4.87.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `fleet 4.87.0`\n\n## Package advisory (CVE-2026-101047)\n\nAffected packages:\n\n- `github.com/fleetdm/fleet/v4 < 4.87.0`\n\nPatched in:\n\n- `github.com/fleetdm/fleet/v4 4.87.0`\n\nSource: https://osv.dev/vulnerability/GHSA-q9c5-pp7m-fm2g","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
