Prior to 2.6.4, OnionShare CLI/Desktop does not enforce the Receive mode disable_files setting in cli/onionshare_cli/web/receive_mode.py, where ReceiveModeRequest._get_file_stream() writes multipart file[] data to disk despite the text-only setting. This issue is fixed in version 2.6.4.","published":"2026-07-31T16:28:06.628Z","modified":"2026-09-12T03:30:50.638840512Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L"},"epss":{"score":0.0028,"percentile":0.20356,"asOf":"2026-09-14"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"onionshare-cli","fixedVersion":"2.6.4"}],"fix":{"url":"https://github.com/onionshare/onionshare/commit/a090e97193efc91fbeac9dace7793ea568b83cf5","label":"onionshare/onionshare@a090e97"},"references":[{"type":"WEB","url":"https://github.com/onionshare/onionshare/releases/tag/v2.6.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54707.json"},{"type":"ADVISORY","url":"https://github.com/onionshare/onionshare/security/advisories/GHSA-v833-3823-cmhp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54707"},{"type":"FIX","url":"https://github.com/onionshare/onionshare/commit/a090e97193efc91fbeac9dace7793ea568b83cf5"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-12T03:30:50.638840512Z"}}
