CVE-2026-114621 · Severity: high · CVSS 8.8 · Published 2026-10-23

baserCMS is a website development framework that many Japanese organizations use to manage their web content. An authenticated admin user can inject malicious SQL code through query parameters in the admin panel and management API, allowing them to extract sensitive data like password hashes from the database. This risk only applies if the admin panel is accessible to untrusted users.

Technical details

The admin and Api/Admin list and detail actions pass request query parameters (contain, conditions, fields, finder, order) directly to the ORM's getIndex() and get() methods without sanitization, allowing SQL injection via the EagerLoader mechanism. An authenticated attacker can embed SQL fragments in these parameters to execute arbitrary queries against the database. The vulnerability was patched in versions 5.3.2 and 5.4.2 by filtering reserved ORM structure keys.
