CVE-2026-45270 | BDVDB-2026-349983 Detail

Description#

CI4MS is a CodeIgniter 4-based content management system skeleton. Prior to version 0.31.9.0, the `Pages` backend module registers the `html_purify` validation rule on language-keyed page content but persists the raw, un-purified POST value into the database. The public renderer for pages (`Home::index()` → `app/Views/templates/default/pages.php`) emits `$pageInfo->content` without `esc()`, yielding stored XSS that fires for every public visitor of the affected page — including administrators. Because pages may be promoted to the site home page, the payload can be served at `/` and reach every visitor of the site. Version 0.31.9.0 patches the issue.
