Machine-written summary

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

Craft CMS (Packagist craftcms/craft) versions 3.5.0 up to 4.16.18, and 5.0.0-RC1 up to 5.8.22, are affected. An authenticated user holding a GraphQL token that is permitted to use the save_images_Asset mutation, with GraphQL enabled, can have the server fetch a URL on a domain they control that resolves to an internal address, such as a cloud metadata service, and save the response as a downloadable file, which can expose sensitive host information such as cloud credentials. Upgrade to Craft CMS 4.16.18 or 5.8.22, which are the fixed versions.
