{"id":"CVE-2026-49244","summary":"SFTPGo: Path confinement bypass in public browsable share partial ZIP download","details":"SFTPGo is an open source, event-driven file transfer solution. From 2.2.0 until 2.7.3, the public web-client partial ZIP download endpoint for a browsable share validates client-supplied files entries with a raw byte-prefix comparison rather than a directory-boundary-aware check. An unauthenticated requester who can reach a public share can select a canonical path outside the shared directory when the target path begins with the shared directory's name, such as a sibling path that shares the same prefix. The endpoint then includes the out-of-scope file in the generated download, disclosing its contents. This issue is fixed in version 2.7.3.","aliases":["GHSA-h64p-8h4r-6gfh","GO-2026-5902"],"modified":"2026-08-23T03:42:38.009031438Z","published":"2026-08-20T21:53:12.098Z","related":["openSUSE-SU-2026:21483-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49244.json","unresolved_ranges":[{"extracted_events":[{"introduced":"\u003e= 2.2.0 \u003c 2.7.2"},{"last_affected":"\u003e= 2.2.0 \u003c 2.7.2"}],"source":"AFFECTED_FIELD"}]},"references":[{"type":"WEB","url":"https://github.com/drakkan/sftpgo/releases/tag/v2.7.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49244.json"},{"type":"ADVISORY","url":"https://github.com/drakkan/sftpgo/security/advisories/GHSA-h64p-8h4r-6gfh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49244"},{"type":"FIX","url":"https://github.com/drakkan/sftpgo/commit/52a56584c417e325aea35ab23849422a90ba512f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/drakkan/sftpgo","events":[{"introduced":"0"},{"fixed":"52a56584c417e325aea35ab23849422a90ba512f"},{"fixed":"a779e504484592d88f510ce7952f4fa18b671e21"}],"database_specific":{"source":"REFERENCES"}}],"versions":["v2.7.1","v2.7.0","v2.6.0","v2.5.1","v2.5.0","v2.4.0","v2.3.0","v2.2.1","v2.2.0","v2.1.0","v2.0.2","v2.0.1","v2.0.0","v1.2.2","v1.2.1","v1.2.0","v1.1.1","v1.1.0","v1.0.0","0.9.6","0.9.5","0.9.4","0.9.3","0.9.2","0.9.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-49244.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
