### Impact
Unauthenticated GraphQL queries for user accounts can expose password hashes of users that have created or modified content, typically but not necessarily limited to administrators and editors.

### Patches
Affected versions: Ibexa DXP v3.3.*, v4.2.*, eZ Platform v2.5.*
Resolving versions: Ibexa DXP v3.3.28, v4.2.3, eZ Platform v2.5.31

### Workarounds
Remove the “passwordHash” entry from “src/bundle/Resources/config/graphql/User.types.yaml” in the GraphQL package, and other properties like hash type, email, login if you prefer.
