CVE-2026-34989: Ci4-cms-erp ci4ms cross-site scripting vulnerability

CCi4 Cms Erp · Ci4ms

CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. Prior to 31.0.0.0, the application fails to properly sanitize user-controlled input when users update their profile name (e.g., full name / username). An attacker can inject a malicious JavaScript payload into their profile name, which is then stored server-side. This stored payload is later rendered unsafely in multiple application views without proper output encoding, leading to stored cross-site scripting (XSS). This vulnerability is fixed in 31.0.0.0.
