{"id":"CVE-2026-49245","summary":"SFTPGo: Stored XSS via inline parameter on public shares and user file download","details":"SFTPGo is an open source, event-driven file transfer solution. From 2.2.0 until 2.7.3, the inline query parameter on browsable-share file downloads and authenticated user-file downloads suppresses Content-Disposition: attachment, allowing an attacker-controlled HTML file stored in a share or home directory to be served as text/html in the SFTPGo web origin. An attacker who can place the file can send a crafted link to a victim, and opening that link executes the stored content in the victim's browser context. Exploitation requires social engineering and suitable share or shared-folder access, while HttpOnly session cookies limit direct cookie theft. This issue is fixed in version 2.7.3.","aliases":["GHSA-3vcg-pv95-pq54","GO-2026-5900"],"modified":"2026-08-23T03:42:56.449844553Z","published":"2026-08-20T21:52:20.219Z","related":["openSUSE-SU-2026:21483-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49245.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"}],"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"]},"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-2026-49245.json"},{"type":"ADVISORY","url":"https://github.com/drakkan/sftpgo/security/advisories/GHSA-3vcg-pv95-pq54"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49245"},{"type":"FIX","url":"https://github.com/drakkan/sftpgo/commit/b5409a478138fca5f1d369ae5d47f753156cbd15"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/drakkan/sftpgo","events":[{"introduced":"0"},{"fixed":"b5409a478138fca5f1d369ae5d47f753156cbd15"},{"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-2026-49245.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:L/I:L/A:N"}]}
