Machine-written summary

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

Craft CMS (craftcms/cms) versions from 4.0.0-RC1 before 4.16.6 and from 5.0.0-RC1 before 5.8.7 are vulnerable to a Twig server-side template injection that may lead to remote code execution. An attacker would need administrator access to the Control Panel, with allowAdminChanges enabled, which Craft CMS advises against in non-development environments. Upgrade to 4.16.6 or 5.8.7, or later.
