Avant Browser and Orca Browser 'browser:home' Multiple HTML Injection Vulnerabilities

Avant Browser and Orca Browser are prone to multiple HTML-injection vulnerabilities because the applications fail to properly sanitize user-supplied input before using it in dynamically generated content.

Attacker-supplied HTML and script code would run in the context of the affected application, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.

The following are vulnerable:
