CVE-2025-54046 is a stored cross-site scripting vulnerability in QuanticaLabs Cost Calculator (versions <= 7.4). It results from improper input neutralization during web page generation, enabling an attacker with low privileges and requiring user interaction to inject malicious scripts. The vulnerability has a CVSS 3.1 score of 6.5, reflecting medium severity with network attack vector, low attack complexity, and partial impact on confidentiality, integrity, and availability. No patch or vendor advisory is currently available, and no known exploits have been reported.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of users viewing the affected pages, potentially leading to partial disclosure of information, modification of data, or disruption of service. The CVSS vector indicates limited but non-negligible impact on confidentiality, integrity, and availability. However, exploitation requires user interaction and low privileges.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting user input that can be stored and rendered, applying web application firewall (WAF) rules to detect and block XSS payloads, and educating users about the risks of interacting with untrusted content. Monitor vendor channels for updates and patches.
