Summary
Craft CMS 5.0.0-RC1 before 5.10.11 GraphQL Entry Mutation Site Scope Bypass
Details

Craft CMS versions before 5.10.11 contain a site scope bypass vulnerability in GraphQL entry mutation resolvers that fail to validate siteId through ArgumentManager::prepareArguments(). Attackers with tokens scoped to one site can read, modify, or delete entries across unauthorized sites by passing siteId directly in mutation arguments.
