Levan Tarbor Forex Calculators versions up to 1.3.6 suffer from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows an attacker with at least low privileges and requiring user interaction to inject malicious scripts that can execute in the context of other users' browsers, potentially leading to partial confidentiality, integrity, and availability impacts. The vulnerability is network exploitable with low attack complexity and partial scope impact.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to partial disclosure of sensitive information, modification of data, or disruption of service. The CVSS vector indicates partial confidentiality, integrity, and availability impacts. No known active exploitation has been reported.
