This vulnerability involves improper neutralization of input in the Themefic Ultimate Addons for Contact Form 7 plugin, allowing cross-site scripting attacks. It affects versions up to and including 3.5.36. The issue relates to incorrect access control configurations that could be leveraged to inject malicious scripts during web page generation. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requires privileges and user interaction, and impacts confidentiality, integrity, and availability at a low level.

Successful exploitation could allow an attacker with some privileges and user interaction to execute arbitrary scripts in the context of the affected web application, potentially leading to partial compromise of confidentiality, integrity, and availability. However, the impact is limited by the requirement for privileges and user interaction, and the overall severity is medium.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. In the absence of an official fix, users should monitor for updates from Themefic and apply patches promptly once available. Until then, consider restricting privileges and user interactions that could trigger the vulnerability.
