Themesgrove WidgetKit Pro versions up to 1.13.1 contain a reflected cross-site scripting vulnerability (CWE-79) due to improper input neutralization during web page generation. This allows attackers to inject malicious scripts that execute when a user interacts with crafted web content. The CVSS 3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to execution of arbitrary scripts in the victim's browser, potentially resulting in partial loss of confidentiality, integrity, and availability of affected systems or data. This may allow attackers to steal sensitive information, manipulate content, or disrupt service from the user's perspective.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should apply standard XSS mitigations such as input validation and output encoding where possible. Monitor vendor channels for updates and apply patches promptly once available.
