Wn backend module: Winter: SQL Injection in Backend Filter Widget numberrange Scope via numbersFromAjax (CVE-2026-32593)
Winter CMS versions up to and including 1.2.12 have a SQL injection vulnerability in the backend Filter widget's numberrange scope when configured with a conditions key. This flaw allows an authenticated backend user to inject arbitrary SQL via the filter's AJAX handler, potentially reading arbitrary database contents. Exploitation requires a third-party plugin to register such a filter scope; a vanilla installation is not affected. The issue is fixed in version 1.2.13.
AI Analysis
Technical Summary
Winter CMS, built on Laravel, has a SQL injection vulnerability (CVE-2026-32593) in the backend Filter widget numberrange scope when configured with a conditions key. The vulnerability arises because filter values are interpolated directly into the SQL conditions without parameter binding, enabling an authenticated backend user to inject arbitrary SQL through the AJAX handler. No default backend views use this vulnerable configuration, so exploitation depends on third-party plugins registering a numberrange filter scope with a conditions key. The vulnerability is fixed in version 1.2.13.
Potential Impact
An authenticated backend user with access to a list view filter using the vulnerable numberrange scope can inject arbitrary SQL queries, potentially reading sensitive database contents. The vulnerability does not allow unauthenticated access and requires specific plugin configurations to be exploitable. There are no known exploits in the wild.
Mitigation Recommendations
Upgrade Winter CMS to version 1.2.13 or later, where this vulnerability is fixed. Since no built-in backend views use the vulnerable scope configuration, installations without third-party plugins registering such filters are not affected. No additional mitigations are required beyond applying the official patch.
