cruddl is software for creating a GraphQL API for a database, using the GraphQL SDL to model a schema. If cruddl starting with version 1.1.0 and prior to versions 2.7.0 and 3.0.2 is used to generate a schema that uses
@flexSearchFulltext, users of that schema may be able to inject arbitrary AQL queries that will be forwarded to and executed by ArangoDB. Schemas that do not use
@flexSearchFulltext are not affected. The attacker needs to have
READ permission to at least one root entity type that has
@flexSearchFulltext enabled. The issue has been fixed in version 3.0.2 and in version 2.7.0 of cruddl. As a workaround, users can temporarily remove
@flexSearchFulltext from their schemas.
