Detailsinfo

A vulnerability classified as problematic was found in baserproject BaserCMS up to 5.3.1/5.4.1. Affected by this vulnerability is an unknown part of the component Admin/Api/Admin Actions. The manipulation of the argument contain/conditions/fields/finder/order with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

baserCMS is a website development framework. In versions 5.0.0 before 5.3.2 and 5.4.0 before 5.4.2, list and detail actions in the Admin and Api/Admin prefixes pass request query parameters, including contain, conditions, fields, finder, and order, directly to the ORM as options. A user able to log into the admin panel can embed SQL fragments in those options to execute arbitrary SQL against the application's database, including reading password hashes from the users table. Public-page and public-API fixes released in 5.3.1 and 5.4.1 did not protect these administrative paths. Setting USE_CORE_ADMIN_API to false does not prevent access through an authenticated browser session. This issue has been patched in versions 5.3.2 and 5.4.2.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-114621 since 10/21/2026. The exploitation appears to be easy. The attack can be launched remotely.
