Description
Craft CMS from 5.0.0 before 5.11.0 contains an authorization bypass vulnerability that allows site-scoped GraphQL tokens to mutate other sites' content because requireAllowedSite() is not enforced. Attackers holding a site-A token can create entries in site B via supplied siteId and delete entries, categories, tags, and assets shared across sites.
