CVE-2026-22804Public exploitNetwork attack vector

Session hijacking and file disclosure via SVG preview

Published Jan 12, 2026 · Updated Jan 12, 2026

Stored XSS in Termix-SSH Termix 1.7.0 through 1.9.0 allows attackers to execute JavaScript by previewing a crafted SVG in File Manager. FileViewer.tsx passes unsanitized SVG content to dangerouslySetInnerHTML, causing embedded event handlers to execute in the application context. Exploitation requires control of a managed SSH host and user preview; browser sessions can be hijacked, while Electron clients expose local files.
