Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Craft CMS (craftcms/cms) versions 5.6.0 up to 5.9.11 are vulnerable to remote code execution through the EntryTypesController action that applies override settings. An attacker needs Craft control panel administrator permissions, and the allowAdminChanges setting must be enabled; the attacker can then inject Yii2 behavior or event handlers to run code. Users should upgrade to Craft CMS 5.9.11.
