CVE-2026-34565 Details
Description
CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. Prior to version 0.31.0.0, the application fails to properly sanitize user-controlled input when adding Posts to navigation menus through the Menu Management functionality. Post-related data selected via the Posts section is stored server-side and rendered without proper output encoding. These stored values are later rendered unsafely within administrative dashboards and public-facing navigation menus, resulting in stored DOM-based cross-site scripting (XSS). This issue has been patched in version 0.31.0.0.
A stored DOM-based cross-site scripting vulnerability has been identified in CI4MS, a CodeIgniter 4-based CMS skeleton, prior to version 0.31.0.0. The issue arises in the Menu Management functionality, where user-controlled input is not properly sanitized when adding posts to navigation menus. This post-related data is stored server-side and rendered without adequate output encoding, allowing malicious JavaScript payloads to execute when the menu is displayed. The vulnerability can lead to privilege escalation in administrative contexts and a full account takeover across all roles.
Users are advised to update to version 0.31.0.0, where this vulnerability has been patched. Additionally, it is recommended to avoid using innerHTML-style JavaScript in PHP applications, as this can create real-world XSS exploitation risks. Implementing Content Security Policy (CSP), and setting cookies as HttpOnly, SameSite, and Secure can help mitigate XSS risks and associated escalated Cross-Site Request Forgery (CSRF) vulnerabilities.
