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.
