CVE-2026-27599: 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 – Mail Settings. Several configuration fields, including Mail Server, Mail Port, Email Address, Email Password, Mail Protocol, and TLS settings, 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
CVE-2026-27599 is a stored cross-site scripting vulnerability (CWE-79) in ci4-cms-erp's ci4ms product. Before version 0.31.0.0, multiple mail configuration fields (Mail Server, Mail Port, Email Address, Email Password, Mail Protocol, and TLS settings) accepted attacker-controlled input that was stored server-side and later rendered without proper output encoding. This improper neutralization of input during web page generation could allow an attacker with high privileges to inject malicious scripts. The issue has been fixed in version 0.31.0.0.
Potential Impact
An attacker with high privileges can inject malicious scripts into mail configuration fields, which are stored and later rendered without proper encoding. This can lead to limited confidentiality, integrity, and availability impacts as indicated by the CVSS vector (C:L/I:L/A:L). However, the attack requires high privileges and no user interaction, limiting the scope of exploitation.
Mitigation Recommendations
Upgrade ci4ms to version 0.31.0.0 or later, where this vulnerability has been patched. No additional mitigation is required if the system is updated. Patch status is confirmed by the vendor advisory indicating the fix in version 0.31.0.0.
