Exploited in the wild: not listed in CISA KEV
EPSS: 0.5% probability of exploitation in the next 30 days

Weakness: CWE-470

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.

Affected products

craftcms cms: from 5.6.0 before 5.9.11 — fixed in 5.9.11

How to fix

Upgrade to a fixed version: craftcms cms 5.9.11. Check the vendor advisory for mitigations.
