CWE: CWE-89 \u2014 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component.

Code:
    public function exists($uuid)
    {
        $queryBuilder = $this->db->createQueryBuilder();
        $queryBuilder
            ->select('uuid')
            ->from(self::TABLE_NAME)
            ->where('uuid = :uuid')
            ->setParameter('uuid', $uuid, Types::STRING);


        $result = $queryBuilder
            ->execute()
            ->fetchOne();

        return (bool) $result;
    }
