CVE-2026-34561: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ci4-cms-erp ci4ms
CVE-2026-34561 is a medium severity cross-site scripting (XSS) vulnerability in ci4ms, a CodeIgniter 4-based CMS skeleton. Versions prior to 0. 31. 0. 0 do not properly sanitize user input in the System Settings – Social Media Management section, allowing attacker-controlled data to be stored and rendered without proper encoding. This can lead to limited confidentiality, integrity, and availability impacts. The issue has been patched in version 0. 31. 0. 0.
AI Analysis
Technical Summary
The vulnerability in ci4ms (versions before 0.31.0.0) involves improper neutralization of input during web page generation (CWE-79). Specifically, multiple configuration fields related to Social Media and Social Media Link accept user-controlled input that is stored server-side and later rendered without proper output encoding. This flaw enables cross-site scripting attacks. The vendor has addressed this issue in version 0.31.0.0.
Potential Impact
Successful exploitation could allow an attacker with high privileges to inject malicious scripts via configuration fields, potentially leading to limited confidentiality, integrity, and availability impacts as indicated by the CVSS vector. However, no known exploits are reported in the wild.
Mitigation Recommendations
Upgrade ci4ms to version 0.31.0.0 or later where this vulnerability has been patched. Since this is not a cloud service, users must apply the update themselves. No additional vendor advisories indicate alternative mitigations or that no action is required.
