CVE-2026-62945: CWE-639: Authorization Bypass Through User-Controlled Key in mauriceboe TREK
CVE-2026-62945 is an authorization bypass vulnerability in mauriceboe TREK, a collaborative travel planner. Before version 3.1.3, the application improperly accepts user-controlled identifiers for reservations, places, and assignments during file upload, update, and linking actions without verifying ownership. This allows an authenticated user with file-edit permissions on any accessible trip to link or reference foreign reservation identifiers, leading to unauthorized disclosure of reservation titles across private trip boundaries. The issue is fixed in version 3.1.3.
AI Analysis
Technical Summary
The vulnerability in mauriceboe TREK occurs because the application does not verify that reservation_id, place_id, and assignment_id values submitted during file-related API calls belong to the trip associated with the file. Specifically, the lack of usage of the findForeignLinkTarget() function allows an attacker with file-edit permissions on any trip to submit foreign reservation identifiers via POST /api/trips/:tripId/files/:id/link, POST /api/trips/:tripId/files, or PUT /api/trips/:tripId/files/:id endpoints. Subsequent retrievals of file links join these foreign reservations and disclose reservation titles, thereby leaking information across trip boundaries. This is classified as CWE-639 (Authorization Bypass Through User-Controlled Key). The vulnerability is addressed in TREK version 3.1.3.
Potential Impact
An authenticated user with file-edit permissions on any accessible trip can exploit this vulnerability to disclose the existence and titles of reservations belonging to other private trips. This results in unauthorized information disclosure (confidentiality impact), but does not affect integrity or availability. The CVSS v3.1 base score is 4.3 (medium severity), reflecting low complexity and low privileges required, with no user interaction needed.
Mitigation Recommendations
This vulnerability is fixed in mauriceboe TREK version 3.1.3. Users and administrators should upgrade to version 3.1.3 or later to remediate this issue. No other mitigation or workaround is indicated by the vendor advisory or CVE data.
