Details

As written in the advisory (Markdown source, shown as plain text).

### Summary The regex validation used to prevent Introspection queries can be bypassed by removing the extra whitespace, carriage return, and line feed characters from the query. ### Details GraphQL Queries in OpenCTI can be validated using the `secureIntrospectionPlugin`. ### Impact Bypassing this restriction allows the attacker to gather a wealth of information about the GraphQL endpoint functionality that can be used to perform actions and/or read data without authorization. These queries can also be weaponized to conduct a Denial of Service (DoS) attack if sent repeatedly.
