CVE-2026-54509: CWE-862: Missing Authorization in mauriceboe TREK
Description
CVE-2026-54509 is a missing authorization vulnerability in mauriceboe TREK versions 3.0.0 up to but not including 3.1.0. The GET /api/journeys/:id/share-link endpoint does not verify if the authenticated user has permission to access the requested journey. This allows any authenticated user to enumerate journey IDs and obtain share tokens for other users' journeys. These tokens enable unauthenticated access to shared journey details such as entries, captions, locations, moods, gallery photos, photo paths, and asset identifiers. The issue is resolved in version 3.1.0.

Technical Analysis
In mauriceboe TREK versions >=3.0.0 <3.1.0, the GET /api/journeys/:id/share-link route returns a share token without checking authorization of the requester. This missing authorization (CWE-862) allows authenticated users to enumerate sequential journey IDs and retrieve share tokens for journeys they do not own. The share tokens grant unauthenticated access to sensitive journey data via GET /api/public/journey/:token. The vulnerability is fixed in version 3.1.0.
Potential Impact
An attacker with ordinary authenticated user privileges can enumerate journey IDs and retrieve share tokens for other users' journeys. These tokens allow unauthenticated access to shared journey information including entries, captions, locations, moods, gallery photos, photo paths, and asset identifiers. This results in unauthorized disclosure of potentially sensitive user data. There is no indication of integrity or availability impact. The CVSS v3.1 base score is 6.5 (medium severity), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and high confidentiality impact.
Mitigation Recommendations
Upgrade mauriceboe TREK to version 3.1.0 or later, where this authorization check issue is fixed. No other mitigations are indicated or required by the vendor advisory. Until patched, restrict access to authenticated users and monitor for unusual enumeration activity if possible.
