Exposure of Private Personal Information (PII) to an unauthorized actor (credit card)
Description
The target application was found to return credit card information in the response. Organizations found returning such information may be in violation of industry regulations and could face fines.
Remediation
PII such as credit cards 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, credit card numbers should
only return 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, credit card information should never be stored un-encrypted in files or databases.
