Description
Craft CMS 4.0.0 before 4.18.9 and 5.0.0 before 5.11.2 contains an SQL injection vulnerability in GraphQL eager-loading: arguments on eager-loadable nodes absent from the public schema are copied into EagerLoadPlan criteria without cleansing. Unauthenticated attackers can supply a parenthesized select argument to inject SQL expressions and read arbitrary database content, including password hashes and session tokens.
