CVE-2026-77293: CWE-639: Authorization Bypass Through User-Controlled Key in mauriceboe TREK
TREK is a collaborative travel planner. Prior to 3.3.0, the DELETE /api/trips/:tripId/collab/notes/:noteId/files/:fileId endpoint authorizes an authenticated user against the attacker-controlled tripId but deleteNoteFile in server/src/services/collabService.ts resolves the target only by note and file identifiers without requiring the file to belong to that trip. A user with edit access to any trip can submit identifiers belonging to another user's trip and permanently delete that note-file attachment. Sequential identifiers make broad targeting practical, while attachment read operations remain trip-scoped and are not affected. This issue is fixed in version 3.3.0.
AI Analysis
Technical Summary
In mauriceboe TREK versions before 3.3.0, the DELETE /api/trips/:tripId/collab/notes/:noteId/files/:fileId endpoint authorizes requests using the tripId parameter controlled by the user. However, the backend service deleteNoteFile resolves the target file solely by noteId and fileId, without confirming that the file belongs to the specified trip. This flaw enables an authenticated user with edit access to any trip to delete note-file attachments from other users' trips by submitting identifiers from those trips. The vulnerability arises from improper authorization checks (CWE-639) and insufficient access control (CWE-862). The vulnerability has a CVSS 3.1 score of 7.1 (High severity) and was fixed in version 3.3.0.
Potential Impact
An authenticated user with edit access to any trip can delete note-file attachments belonging to other users' trips. This results in unauthorized modification of data (integrity impact) and partial denial of availability for those attachments. Confidentiality is not affected. The vulnerability does not allow reading or accessing attachments outside the authorized trip scope.
Mitigation Recommendations
Upgrade mauriceboe TREK to version 3.3.0 or later, where this authorization bypass vulnerability is fixed. Prior to upgrading, restrict edit access to trusted users only to limit potential abuse. Patch status is confirmed fixed in version 3.3.0.
