## What is CVE-2026-44010?

CVE-2026-44010 is a high-severity missing authorization vulnerability in craftcms cms, published on 12 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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.

Weakness: CWE-862 (Missing Authorization)
