CVE-2026-34569 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 when creating or editing blog categories. An attacker can inject a malicious JavaScript payload into the category title field, which is then stored server-side. This stored payload is later rendered unsafely across public-facing blog category pages, administrative interfaces, and blog post views without proper output encoding, leading to stored cross-site scripting (XSS). This issue has been patched in version 0.31.0.0.
A stored cross-site scripting vulnerability has been identified in CI4MS, a CodeIgniter 4-based CMS, prior to version 0.31.0.0. The issue arises because the application does not properly sanitize user input when creating or editing blog categories. This allows an attacker to inject a malicious JavaScript payload into the category title, which is then stored on the server. The injected payload is later executed unsafely on public-facing blog category pages, administrative interfaces, and blog post views, leading to persistent cross-site scripting. This vulnerability can escalate privileges when viewed by administrators or privileged users, potentially allowing a full account takeover.
Users are advised to update to version 0.31.0.0, where this vulnerability has been patched. After updating, it is recommended to back up the database and run 'composer update' before upgrading.
