PublishedSFTPGo 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.
