Probability of exploitation in the next 30 days: 0.32% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
Fixed version: apostrophecms apostrophe 3.7.1.

Low priority for now. Upgrade to apostrophecms apostrophe 3.7.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
