What is CVE-2026-34568?

The CI4MS CMS, built on CodeIgniter 4, suffers from a stored cross-site scripting vulnerability due to inadequate sanitization of user-controlled input in blog posts. Prior to version 0.31.0.0, an attacker can exploit this flaw to inject malicious JavaScript into blog content. The harmful payload is saved on the server and later displayed unsafely across various application views. Proper output encoding measures were not implemented, resulting in a risk of user data compromise and session hijacking. Users are encouraged to update to version 0.31.0.0 to mitigate this threat.
