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 acce","public_affected_ranges":["< 4.87.0"]}],"null_published_at":"2026-11-02T10:00:37.192Z","source_updated_at":"2026-08-20T18:44:34.000Z","source_disclosed_at":"2026-08-20T18:44:31.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-02T09:56:46.713Z"}],"next_cursor":null,"snapshot_revision":"42594"}
