CVE-2026-34989: 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 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.
AI Analysis
Technical Summary
CI4MS versions before 31.0.0.0 fail to neutralize user input properly when users update their profile names, leading to stored cross-site scripting (CWE-79). Malicious JavaScript injected into profile names is stored on the server and later rendered without proper output encoding in various application views. This allows attackers to execute arbitrary scripts in the context of other users' browsers. The vulnerability is fixed in version 31.0.0.0.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of other users, potentially leading to session hijacking, credential theft, or other malicious actions within the application. The vulnerability is rated critical with a CVSS 4.0 score of 9.4, indicating high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade to ci4ms version 31.0.0.0 or later, where the vulnerability is fixed. Since no official patch or temporary fix details are provided beyond this version update, applying this upgrade is the recommended remediation. Patch status is not explicitly confirmed beyond the version fix; verify with the vendor advisory for the latest remediation guidance.
