## Overview

### 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.

## Affected packages

- `pycti < 6.1.9`

## Remediation

Upgrade to a patched release:

- `pycti 6.1.9`
