Description · from the CVE record

Craft CMS from 5.0.0 before 5.11.2 contains an authorization bypass vulnerability that allows anonymous GraphQL clients to read out-of-scope section entries via prev/next fields. Attackers can chain next hops from one visible in-scope entry to enumerate entries and read titles, slugs, and custom-field content from withheld sections.
