# Exposure of Private Personal Information (PII) to an unauthorized actor (United States social security number)
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
The target application was found to return social security number (SSN) information in the response. Organizations
|
||
|
|
found returning such information may be in violation of (United States) state or federal laws and may face stiff penalties.
|
||
|
|
|
||
|
|
## Remediation
|
||
|
|
|
||
|
|
PII such as social security numbers should never be directly returned to the user. The majority of the information
|
||
|
|
should masked except the last few digits or characters of the identifier. For example, social security numbers
|
||
|
|
only be displayed with the last four digits: `***-**-1234`. Ensure this masking is done on the server
|
||
|
|
and only then send the masked data back to the client. Do not rely on client side JavaScript or other methods
|
||
|
|
to mask these values as the data could still be intercepted or unmasked.
|
||
|
|
|
||
|
|
Additionally, social security numbers should never be stored un-encrypted in files or databases.
