CVE-2026-34562: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ci4-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 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.
AI Analysis
Technical Summary
The ci4ms CMS prior to version 0.31.0.0 contains a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of user input in administrative configuration fields under System Settings – Company Information. This allows an attacker with administrative privileges to inject malicious scripts that are stored on the server and executed when rendered. The issue has been fixed in version 0.31.0.0.
Potential Impact
Successful exploitation could lead to limited confidentiality, integrity, and availability impacts as indicated by the CVSS vector (C:L/I:L/A:L). Specifically, an attacker with administrative privileges could execute arbitrary scripts in the context of the application, potentially leading to session hijacking, defacement, or other client-side impacts. No known exploits in the wild have been reported.
Mitigation Recommendations
Upgrade ci4ms to version 0.31.0.0 or later, where this vulnerability has been patched. No other mitigation is required as the fix is officially available.
