The Weather Atlas Widget versions up to 3.0.3 suffer from a reflected cross-site scripting vulnerability caused by improper input neutralization during web page generation. This allows attackers to inject malicious scripts that execute in users' browsers when they interact with the widget, potentially leading to information disclosure, manipulation, or disruption of service. The CVSS 3.1 base score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and scope changed. No patch or vendor advisory is currently provided, and the product is not a cloud service.

Successful exploitation of this vulnerability can lead to partial compromise of confidentiality, integrity, and availability of affected systems or user data through execution of arbitrary scripts in the context of the vulnerable web widget. This may enable attackers to steal sensitive information, manipulate content, or disrupt service for users interacting with the widget.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch or official fix is available, users should consider disabling or removing the Weather Atlas Widget if feasible, or applying web application firewall (WAF) rules to detect and block reflected XSS payloads targeting the widget. Monitor vendor communications for updates on patches or official mitigations.
