Summary:The WordPress plugin TC Custom JavaScript is prone to a cross-site scripting (XSS) vulnerability.
Description:Summary:
The WordPress plugin TC Custom JavaScript is prone to a cross-site scripting (XSS) vulnerability.

create a new, malicious administrator user account leading to takeover of the entire site.
