Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
ApostropheCMS's @apostrophecms/import-export package, versions before 3.7.1, exposes a POST route for cleaning up exports that lacks authentication and authorization checks. Per the source, an anonymous user holding the site's standard CSRF cookie could call it to delete temporary export files on the server and change job and notification records without any ownership check. Upgrade to @apostrophecms/import-export 3.7.1 or later, which the source lists as the fixed version.
