CVE-2026-34562 · Severity: medium · CVSS 4.7 · Published 2026-04-01

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 within System Settings – Company Information. Several administrative configuration fields accept attacker-controlled input that is stored server-side and later rendered without proper output encoding. This issue has been patched in version 0.31.0.0.

Technologies: Ci4-Cms-Erp Ci4ms, ci4-cms-erp/ci4ms (Packagist). Vendors: Ci4-Cms-Erp, Packagist.
