CVE-2026-62945Network attack vector

Reservation-title disclosure via unvalidated cross-trip file links

Published Aug 20, 2026 · Updated Aug 20, 2026

Authorization bypass in Liketrek TREK 3.1.2 and earlier allows remote authenticated users to disclose cross-trip reservation titles via file links. FilesController stores attacker-controlled reservation, place, and assignment identifiers without verifying that each object belongs to the file's trip; later joins return the foreign reservation title. Normal users need file-edit access only on an accessible trip, and the exposure is limited to reservation existence and titles rather than full records, file contents, or write access.
