CVE-2025-56515 is a stored cross-site scripting vulnerability in the Fiora chat application affecting version 1.0.0 through the avatar upload functionality. The application permits SVG image uploads for user avatars but does not properly validate or sanitize SVG content. An attacker can upload a crafted SVG containing active content, specifically foreignObject elements with iframe tags and JavaScript event handlers such as onmouseover. Because the malicious SVG is stored by the application and later rendered in other users' browsers when they view the attacker's profile or avatar, the embedded script executes in the security context of the Fiora application.
