{"id":"CVE-2026-49244","aliases":["GHSA-h64p-8h4r-6gfh","GO-2026-5902"],"url":"https://o3.security/vulnerability/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.","published":"2026-08-20T21:53:12.098Z","modified":"2026-08-23T03:42:38.009031438Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.0037,"percentile":0.30383,"asOf":"2026-09-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/drakkan/sftpgo/v2","fixedVersion":"2.7.3"}],"fix":{"url":"https://github.com/drakkan/sftpgo/commit/52a56584c417e325aea35ab23849422a90ba512f","label":"drakkan/sftpgo@52a5658"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-23T03:42:38.009031438Z"}}
