This vulnerability involves a CSRF flaw in the Casey Johnson Loan Calculator's repayment-calculator feature that enables stored XSS attacks. The affected versions are up to 1.3. The CVSS 3.1 vector indicates the attack can be performed remotely over the network without privileges but requires user interaction. The vulnerability impacts confidentiality, integrity, and availability with low to medium impact levels. No vendor advisory or patch information is available at this time.

Successful exploitation could allow an attacker to execute stored XSS attacks via CSRF, potentially leading to unauthorized actions performed in the context of an authenticated user. This can result in partial compromise of confidentiality, integrity, and availability of the affected system. The CVSS score of 7.1 reflects a high severity due to these combined impacts.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider implementing CSRF protections such as anti-CSRF tokens and input validation to mitigate the risk of stored XSS via CSRF. Monitor vendor channels for updates and patches.
