ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.0 of the import-export module, an authenticated importer can submit a tar entry whose normalized destination targets a directory while bypassing the literal parent-path substring guard. Opening that directory as a write stream emits an unhandled filesystem error that can terminate the Node.js process; the source establishes this static primitive but not an end-to-end exploit or controlled arbitrary file read or write. This issue is fixed in version 3.7.0.
