CVE-2026-45139

CVE-2026-45139 · CI4MS Fileeditor allows deletion and rename of critical application files due to missing extension allowlist on destructive operations

This page contains facts from public vulnerability sources. Check the original advisory before updating.

CI4MS is a CodeIgniter 4-based content management system skeleton. Prior to version 0.31.9.0, the Fileeditor module enforces an extension allowlist (`['css','js','html','txt','json','sql','md']`) on content-write operations (`saveFile`, `createFile`), but two destructive endpoints — `deleteFileOrFolder` and `renameFile` — never validate the extension of the *source* path. A backend user with file-editor permissions can therefore unlink or rename any file inside the project root that is not explicitly listed in the small `$hiddenItems` blocklist. Critical framework files such as `app/Config/Routes.php`, `app/Config/App.php`, `app/Config/Database.php`, `app/Config/Filters.php`, `public/index.php`, and `public/.htaccess` all live outside that blocklist and can be destroyed, producing a persistent denial of service that requires filesystem-level redeployment to recover. Version 0.31.9.0 patches the issue.
