CSSTidy and ImpressCMS Cross-Site Scripting Vulnerability

CSSTidy is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

Mitigation:

It is recommended to update CSSTidy and ImpressCMS to the latest versions available, which should address this vulnerability. Additionally, input validation and output encoding should be implemented to mitigate cross-site scripting vulnerabilities.
