    "summary": "#### 1. Summary The API endpoint `POST /api/v1/@apostrophecms/import-export/clean-export` in `@apostrophecms/import-export` lacks authentication and authorization checks. Any client—including unauthenticated anonymous users who have obtained the standard CSRF cookie from visiting the site—can directly invoke this route and trigger the underlying `self.cleanExport(req)` method. --- #### 2. Affected Files & Endpoints * **Endpoint:** `POST /api/v1/@apostrophecms/import-export/clean-export` * **Route Definition:** `packages/import-export/lib/apiRoutes.js` (lines 32–34) * **Method Implementation:** `packages/import-export/lib/methods/import.js` (lines 1271–1324) --- #### 3. Root Cause Analysis In `packages/import-export/lib/apiRoutes.js`, the `get.related` handler explicitly validates that the caller is logged in: ```javascript get: { async related(req) { if (!req.user) { throw self.apos.error('forbidden'); } // ... } } ``` In contrast, `post.cleanExport` (as well as `post.overrideDuplicates`) lacks any verification of `req.user`: ```javascript post: { async overrideDuplicates(req) { return self.overrideDuplicates(req); }, async cleanExport(req) { return self.cleanExport(req); // <-- No authentication check } } ``` Because ApostropheCMS does not enforce authentication globally on all `apiRoutes`, omitting an explicit `if (!req.user)` guard allows anonymous requests to pass directly through to the business logic layer. --- #### 4.
