CompactCMS is prone to multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied input.

Attacker-supplied script code may be executed in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials.

CompactCMS 1.4.1 is vulnerable; other versions may also be affected.
