What happened

#### 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); // { get: { ... }, post: { async overrideDuplicates(req) { + if (!req.user) { + throw self.apos.error('forbidden'); + } return self.overrideDuplicates(req); },

async cleanExport(req) { + if (!req.user) { + throw self.apos.error('forbidden'); + } return self.cleanExport(req); } } ```

Affected package ranges reported by GitHub: @apostrophecms/import-export: < 3.7.1

About this data

This record was ingested from a data source. Retrieved: Oct 26, 2026, 19:40 UTC. Ingestion is not an independent editorial investigation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
