CVE-2026-44010

Craft CMS: Missing Authorization in GraphQL Address Resolver Allows Cross-Scope PII Disclosure

Published May 12, 2026 CVSS 4.0 · 7.1 High EPSS < 1% KEV · Not listed
Description
Craft CMS is a content management system (CMS). From 4.0.0 to before 4.17.12 and 5.9.18, the GraphQL Address element resolver (src/gql/resolvers/elements/Address.php) performs no schema scope filtering on top-level queries. A GraphQL API token scoped to a single low-privilege user group can read every address in the system, including addresses belonging to users in groups the token has no authorization to access. This exposes PII, including full names, addresses, organizations, tax IDs, etc. This vulnerability is fixed in 4.17.12 and 5.9.18.
