HTML Injection Vulnerability in MonoChat

The MonoChat application is prone to an HTML-injection vulnerability because it fails to properly sanitize user-supplied input before using it in dynamically generated content. This allows an attacker to inject malicious HTML and script code, which would be executed in the context of the affected website. This could potentially lead to the theft of cookie-based authentication credentials or control over how the site is rendered to the user. Other attacks may also be possible.

Mitigation:

To mitigate this vulnerability, it is recommended to sanitize and validate user-supplied input before using it in dynamically generated content. This can be achieved by implementing proper input validation and output encoding techniques.
