Alert meAnalysisAIv1 – Mar 12, 2026
Stored XSS in Termix File Manager (versions 1.7.0-1.9.0) allows attackers with SSH server access to execute arbitrary JavaScript by uploading malicious SVG files that bypass content sanitization. When a Termix user previews the crafted file, the payload executes within the application context with full access to sensitive operations. Public exploit code exists and no patch is currently available.

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 1.7.0 to 1.9.0, Stored Cross-Site Scripting (XSS) vulnerability exists in the Termix File Manager component. The application fails to sanitize SVG file content before rendering it. This allows an attacker who has compromised a managed SSH server to plant a malicious file, which, when previewed by the Termix user, executes arbitrary JavaScript in the context of the application. The vulnerability is located in src/ui/desktop/apps/file-manager/components/FileViewer.tsx. This vulnerability is fixed in 1.10.0.
Executive ViewAI
Organizations using Termix face notable risk from CVE-2026-22804, a cross-site scripting vulnerability rated CVSS 8.0. Attackers could inject malicious scripts to steal user sessions, credentials, or perform actions on behalf of authenticated users. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates when available and consider compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Implement Content-Security-Policy headers; (2) Enable HttpOnly and SameSite cookie attributes; (3) Deploy WAF XSS/CSRF rules.
