Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
cruddl is software for creating a GraphQL API for a database, using the GraphQL SDL to model a schema. If cruddl versions 1.1.0 prior to 2.7.0, 3.0.0 prior to 3.0.1 and 3.7.2-optimize-delete-queries.0 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 2.7.0 and 3.0.1 of cruddl. As a workaround, users can temporarily remove `@flexSearchFulltext` from their schemas.
CWE-74 - Injection
Listed as the number one web application security risk on the 'OWASP Top Ten', injection attacks are widespread and dangerous, especially in legacy applications. Injection attacks are a class of vulnerabilities in which an attacker injects untrusted data into a web application that gets processed by an interpreter, altering the program's execution. This can result in data loss/theft, loss of data integrity, denial of service, and even compromising the entire system.
