## What is CVE-2026-113648?

CVE-2026-113648 is a low-severity vulnerability in @apostrophecms apostrophe, published on 20 Oct 2026. 

### Official description

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.

Weakness: CWE-862 (Missing Authorization), CWE-306 (Missing Authentication for Critical Functionality)
