The Webilop User Language Switch component suffers from a reflected XSS vulnerability due to improper input neutralization during web page generation. This vulnerability affects versions up to 1.6.10 and allows attackers to inject malicious scripts that execute when a user interacts with the language switch feature. The CVSS 3.1 score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to execution of arbitrary scripts in the context of the victim's browser session, potentially resulting in theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability to a limited extent. The reflected nature requires user interaction, and no known exploits are currently reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. In the absence of an official patch or advisory, users should consider applying input validation and output encoding controls on the User Language Switch component to mitigate reflected XSS risks. Monitor vendor channels for updates and apply official fixes once available.
