CVE-2026-113648

ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.1 of the import-export module, 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. This issue is fixed in version 3.7.1.

Prior to 3.7.1 of the import-export module, 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. This issue is fixed in version 3.7.1.

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:

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:

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. Evidence

When sending an unauthenticated POST request with the site’s CSRF cookie (issued to any visitor on GET /), the request bypasses access control entirely and executes self.cleanExport(req), as demonstrated by the server stack trace:

at Object.cleanExport (.../packages/import-export/lib/methods/import.js)
at .../packages/apostrophe/modules/@apostrophecms/module/index.js:193:30

This confirms that execution directly reaches the core import-export handler without an authenticated session.

5. Impact

1. Broken Access Control: Unauthenticated users can invoke cleanup operations and delete temporary export files and artifacts stored on the server.
2. Unauthorized State Mutation: The endpoint allows modifying job records in the database via req.body.jobId (forcing them to ended: true, status: 'completed') and dismissing notifications via req.body.notificationId without verifying whether the resources belong to the requesting caller.

6. Suggested Remediation (Patch)

Enforce an authentication check in packages/import-export/lib/apiRoutes.js before executing the underlying methods:
