{"cve":"CVE-2026-49244","nvd":{"published":"2026-08-20T22:17:19.947","modified":"2026-10-18T20:10:00.110","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9},"cwes":["CWE-22"],"references":["https://github.com/drakkan/sftpgo/commit/52a56584c417e325aea35ab23849422a90ba512f","https://github.com/drakkan/sftpgo/releases/tag/v2.7.3","https://github.com/drakkan/sftpgo/security/advisories/GHSA-h64p-8h4r-6gfh"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-49244","score":0.00448,"percentile":0.38649,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-h64p-8h4r-6gfh","url":"https://osv.dev/vulnerability/GHSA-h64p-8h4r-6gfh","summary":"SFTPGo has path confinement bypass in public browsable share partial ZIP download","modified":"2026-07-07T16:11:33.267968532Z","packages":[{"ecosystem":"Go","name":"github.com/drakkan/sftpgo/v2","purl":"pkg:golang/github.com/drakkan/sftpgo/v2","ranges":[">=2.2.0 <2.7.3"],"fixed":["2.7.3"]}]},{"id":"GO-2026-5902","url":"https://osv.dev/vulnerability/GO-2026-5902","summary":"SFTPGo has path confinement bypass in public browsable share partial ZIP download in github.com/drakkan/sftpgo","modified":"2026-07-07T16:00:36.718914105Z","packages":[{"ecosystem":"Go","name":"github.com/drakkan/sftpgo","purl":"pkg:golang/github.com/drakkan/sftpgo","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/drakkan/sftpgo/v2","purl":"pkg:golang/github.com/drakkan/sftpgo/v2","ranges":[">=2.2.0 <2.7.3"],"fixed":["2.7.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
