CVE-2026-77320Public exploitNetwork attack vectorHinoki check available

Trip itinerary disclosure via unenforced share permission

Published Sep 24, 2026 · Updated Sep 24, 2026

Improper access control in Liketrek TREK before 3.3.0 allows remote attackers with a valid share token to read hidden trip data. getSharedTripData returns days, assignments, dayNotes, and place details from GET /api/shared/:token without applying the owner's share_map setting. Possession of the random share token is required; the read-only flaw discloses itinerary, coordinates, addresses, notes, and prices but does not modify data.
