It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-22810 exists.\n\nAffected packages and fixed versions:\n- @joplin/onenote-converter (npm): affected all versions; fixed in 3.5.7\n- @joplin/onenote-converter (npm): affected all versions; fixed in 3.5.7\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-22810/ (Markdown: https://insights.sbomify.com/CVE-2026-22810/index.md)","id":"CVE-2026-22810","markdown":"https://insights.sbomify.com/CVE-2026-22810/index.md","name":"CVE-2026-22810","record":{"aliases":["GHSA-gcmj-c9gg-9vh6"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Joplin note-taking app","requires_auth":"low_privilege","summary":"Attackers can overwrite arbitrary files via malicious OneNote imports due to unsanitized filenames in Joplin.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"joplin","vendor":"joplinapp"},{"product":"one2html","vendor":"msiemens"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-24","name":"Path Traversal: '../filedir'"}],"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.
