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 group and role management functionality. Multiple input fields (three distinct group-related fields) can be injected with malicious JavaScript payloads, which are then stored server-side. These stored payloads are later rendered unsafely within privileged administrative views without proper output encoding, leading to stored cross-site scripting (XSS) within the role and permission management context. This issue has been patched in version 0.31.0.0.
Analysis
Stored cross-site scripting in CI4MS role/group management allows authenticated attackers to inject malicious JavaScript into three distinct administrative fields, achieving persistent code execution in privileged admin contexts with scope change impact. The vulnerability affects all versions prior to 0.31.0.0 and requires low-privilege authenticated access with no user interaction (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C). …
