CVE-2026-34561 Details
Description
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 – Social Media Management. Multiple configuration fields, including Social Media and Social Media Link, 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.
A stored DOM-based cross-site scripting vulnerability has been identified in CI4MS, a CodeIgniter 4-based CMS skeleton, prior to version 0.31.0.0. The issue arises in the System Settings – Social Media Management section, where multiple configuration fields allow the injection of attacker-controlled input. This input is stored server-side and rendered without proper output encoding, enabling the execution of malicious scripts. Unlike typical stored cross-site scripting vulnerabilities that execute on public-facing pages, this issue manifests immediately on the same settings page, breaking out of the input attribute context and executing in the browser of the user managing the settings.
Users are advised to update to version 0.31.0.0, where this vulnerability has been patched.
