This vulnerability in falselight Exchange Rates (<= 1.2.5) involves improper neutralization of input during web page generation, resulting in stored cross-site scripting (XSS). An attacker could inject malicious scripts that persist on the server and execute in the browsers of users who access the affected pages. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring low privileges and user interaction, with impact on confidentiality, integrity, and availability at a low level.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of affected users, potentially leading to information disclosure, session hijacking, or other impacts on user confidentiality, integrity, and availability. The impact is rated medium severity with a CVSS score of 6.5. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor for vendor updates and apply patches once available. In the meantime, applying web application firewalls or input validation controls may help mitigate risk but are not substitutes for a vendor fix.
