CVE-2026-41890

What it is

CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. From version 0.31.1.0 to before version 0.31.8.0, the deleteProcess() action accepts a POST parameter tables[] containing arbitrary table names. These are passed directly to $forge->dropTable() without validating that the tables belong to the theme being deleted. The deleteConfirm view correctly populates tables[] from the theme's own migration files, but the server-side deleteProcess does not verify the received values against those files. An authenticated admin can craft a POST request with arbitrary table names and drop any table in the database. This issue has been patched in version 0.31.8.0.
