Cleartext submission of sensitive information- checkmarx java

I am not able to find solution for jsp file.

2. Social Security Number:
3. ${applicant.ssn}

Getting checkmarx issue at line 3.

Potentially sensitive personal information getssn at line 3 is sent over the unsecured network by BinaryExpr in

${applicant.ssn}. This could expose the personal data and allow it to be stolen.

I want the solution for this issue.⁷
