  "details": "## Summary\n\nThe inline query parameter on the browsable-share file download and on the authenticated user file download suppressed Content-Disposition: attachment, so an HTML file stored in a share or home directory could be served as text/html and execute in SFTPGo\u0027s web origin (stored XSS).\n\n## Impact\n\nLow. Exploitation requires the attacker to place the file and a victim to open the crafted link \u2014 a URL the WebClient never generates, so it requires social engineering \u2014 and the practical conditions are narrow:\n\n- Session cookies are HttpOnly, so the cookie cannot be read by the injected script.\n- Authenticated shares set their own session cookie, which overwrites the victim\u0027s WebClient cookie, no account pivot. The realistic case is a public share, or a folder shared between distinct users combined with targeted social engineering.\n\nIt is a genuine trust-boundary violation (SFTPGo emits attacker-controlled content as active HTML in its own origin), hence an advisory, but the constrained preconditions and the HttpOnly mitigation keep it Low.\n\n## Patches\n\nUpgrade to v2.7.3. These endpoints now always respond with Content-Disposition: attachment; the inline parameter has been removed. See the fix commit for the full technical rationale.",
