CVE-2026-35035 (GCVE-0-2026-35035)

Vulnerability from cvelistv5 – Published: 2026-04-06 16:49 – Updated: 2026-04-08 14:26

Title

CI4MS Company Information Public-Facing Page Full Platform Compromise & Full Account Takeover for All Roles & Privilege-Escalation via System Settings Company Information Stored DOM XSS

Summary

CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. Prior to 0.31.2.0, 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. These values are persisted in the database and rendered unsafely on public-facing pages only, such as the main landing page. There is no execution in the administrative dashboard—the vulnerability only impacts the public frontend. This vulnerability is fixed in 0.31.2.0.

Severity

7.2 (High)
