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."}], "lastModified": "2026-06-02T17:04:00.330", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:joplinapp:joplin:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "864FE8BA-88B5-4C60-BEAA-DA2B104AA7B6", "versionEndExcluding": "3.5.7"}, {"criteria": "cpe:2.3:a:msiemens:one2html:*:*:*:*:*:rust:*:*", "vulnerable": true, "matchCriteriaId": "388B685F-E69E-455C-A6DF-C44652AC77C2", "versionEndIncluding": "1.3.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
