How to fix

Technical details

The vulnerability exists in the GraphQL entry mutation resolver (src/gql/resolvers/mutations/Entry.php), where the site-scope check via requireAllowedSite() is only enforced on the update branch but missing from the create branch. An attacker with a site-A scoped token can supply an arbitrary siteId parameter to create entries directly in site B, and delete entries, categories, tags, and assets shared across sites. The vulnerability affects all mutations that bypass the scope enforcement check.

Affected products

Craft CMS CMS 5.0.0 before 5.11.0
