CVE-2026-32593

## Impact The Backend Filter widget (`Backend\Widgets\Filter`) is vulnerable to SQL injection through the `numberrange` scope type when the scope is configured with a `conditions` key. An authenticated backend user with access to a list view containing a vulnerable filter scope can inject arbitrary SQL via the filter's AJAX handler, potentially gaining read access to the full database contents. To exploit this, an attacker must have a valid backend account with access to a list view where a third-party plugin has registered a `numberrange` filter scope using the `conditions` configuration key. No built-in Winter CMS backend views use this scope type and configuration combination, so a vanilla installation without plugins is not exploitable. ## Patches This issue has been fixed in Winter CMS v1.2.13. ## Workarounds If users cannot upgrade, they may apply commit https://github.com/wintercms/winter/commit/50713de95adf5298536d93f4d999652525d36d43 to your Winter CMS installation manually to resolve this issue.
