Summary
CherryTree through 1.7.2 contains a path traversal vulnerability in CtStorageXmlHelper::_create_image_from_xml that trusts unvalidated embedded-file 'filename' attributes in XML documents. Attackers can craft a .ctd, .ctz, or .ctx document with an absolute or ~/ filename and no data, so saving embeds files like ~/.ssh/id_rsa into the document.
