Summary
CI4MS: Unrestricted PHP File Upload via Theme Installation Leads to Authenticated Remote Code Execution
Details

CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. From version 0.26.0.0 to before version 0.31.7.0, a theme upload feature allows any authenticated backend user with theme-upload permission to achieve remote code execution (RCE) by uploading a crafted ZIP file. PHP files inside the ZIP are installed into the web-accessible public/ directory with no extension or content filtering, making them directly executable via HTTP. This issue has been patched in version 0.31.7.0.
