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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","score":7.3},"cwes":["CWE-24"],"references":["https://github.com/laurent22/joplin/blob/af5108d70233b1db9410346958c1587cf7c1b16d/packages/onenote-converter/renderer/src/page/embedded_file.rs#L13-L16","https://github.com/laurent22/joplin/commit/791668455e1aae50501ff57ea4783b3fba9d377c","https://github.com/laurent22/joplin/pull/13736","https://github.com/laurent22/joplin/releases/tag/v3.5.7","https://github.com/laurent22/joplin/security/advisories/GHSA-gcmj-c9gg-9vh6"],"products":["joplinapp:joplin","msiemens:one2html"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-22810","score":0.00206,"percentile":0.1068,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-gcmj-c9gg-9vh6","url":"https://osv.dev/vulnerability/GHSA-gcmj-c9gg-9vh6","summary":"@joplin/onenote-converter: Path traversal in OneNote importer allows overwriting arbitrary files","modified":"2026-09-10T03:51:05.689991880Z","packages":[{"ecosystem":"npm","name":"@joplin/onenote-converter","purl":"pkg:npm/%40joplin/onenote-converter","ranges":["<3.5.7"],"fixed":["3.5.7"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
