Description
CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. Prior to 0.31.4.0, the Pages module does not apply the html_purify validation rule to content fields during create and update operations, while the Blog module does. Page content is stored unsanitized in the database and rendered as raw HTML on the public frontend via echo $pageInfo->content. An authenticated admin with page-editing privileges can inject arbitrary JavaScript that executes in the browser of every public visitor viewing the page. This vulnerability is fixed in 0.31.4.0.
