CMS Made Simple is prone to an HTML-injection vulnerability because it fails to sanitize user-supplied input.
Attacker-supplied HTML or JavaScript code could run in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials and control how the site is rendered to the user; other attacks are also possible.
CMS Made Simple 1.10.3 is vulnerable; other versions may also be affected.
