## What is CVE-2026-32263?

CVE-2026-32263 is a high-severity code injection vulnerability in Craftcms Craft Cms, published on 16 Mar 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Craft CMS is a content management system (CMS). From version 5.6.0 to before version 5.9.11, in src/controllers/EntryTypesController.php, the $settings array from parse_str is passed directly to Craft::configure() without Component::cleanseConfig(). This allows injecting Yii2 behavior/event handlers via "as" or "on" prefixed keys, the same attack vector as the original advisory. Craft control panel administrator permissions and allowAdminChanges must be enabled for this to work. This issue has been patched in version 5.9.11.

Weakness: CWE-470 (Use of Externally-Controlled Input to Select Classes or Code)
