{"id":"CVE-2026-54706","summary":"OnionShare follows symlinks in shared directories, allowing unintended disclosure of local files","details":"OnionShare is an open source tool that lets you securely and anonymously share files, host websites, and chat with friends using the Tor network. Prior to 2.6.4, OnionShare CLI/Desktop follows symbolic links in cli/onionshare_cli/web/send_base_mode.py through SendBaseModeWeb.set_file_info() and stream_individual_file(), allowing remote recipients of Share or Website mode to read local files outside the selected directory. This issue is fixed in version 2.6.4.","aliases":["GHSA-22p9-r2f5-22mf","PYSEC-2026-3585"],"modified":"2026-08-12T03:51:39.177404678Z","published":"2026-07-31T16:30:58.062Z","related":["openSUSE-SU-2026:11169-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-59"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54706.json"},"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-2026-54706.json"},{"type":"ADVISORY","url":"https://github.com/onionshare/onionshare/security/advisories/GHSA-22p9-r2f5-22mf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54706"},{"type":"FIX","url":"https://github.com/onionshare/onionshare/commit/48f31cfac077fcc9c04c67c2a6dbf87d956f5eec"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/onionshare/onionshare","events":[{"introduced":"0"},{"fixed":"48f31cfac077fcc9c04c67c2a6dbf87d956f5eec"},{"fixed":"abc798f3fc449154f31509c7ec23267db0ebeefc"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.6.4"}]}}],"versions":["v2.6.3","v0.9","v0.8.1","0.8","0.7.1","0.7","0.6","0.5","0.4","0.3","0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54706.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:N/A:N"}]}
