AI-suggested
A fix is available in Joplin version 3.5.7. Users and administrators should upgrade to version 3.5.7 or later to remediate this vulnerability. Since this is not a cloud service, patching the client application is required. There is no vendor advisory content explicitly stating otherwise. Until upgraded, avoid importing untrusted OneNote (.one) files to mitigate risk.
Description
Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Versions prior to 3.5.7 contain a path traversal vulnerability in the importer which allows overwriting arbitrary files on disk. The OneNote converter does not sanitize the names of embedded files before writing them to disk. As a result, it's possible for an attacker to create a malicious .one file that includes file names containing ../../, that are then interpreted as part of the target path when extracting attachments from the .one file. This issue has been patched in version 3.5.7.
