CVE-2026-118693 Details
Description
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.
A path traversal vulnerability has been identified in CherryTree versions through 1.7.2. The issue resides in the 'CtStorageXmlHelper::_create_image_from_xml' function, which improperly validates embedded-file 'filename' attributes in XML documents. This vulnerability allows attackers to create .ctd, .ctz, or .ctx files with absolute or home directory paths that, when the document is saved, can embed sensitive files, such as the SSH private key, into the CherryTree document.
Users are advised to update to CherryTree version 1.7.3 or later, where this vulnerability has been addressed.
