# CVE-2026-118693: CherryTree through 1.7.2 Local File Disclosure via Embedded-File Filename Path

Status: published. Published: 2026-10-28. Updated: 2026-11-03.

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.
