The WP Frontend Submit plugin (<= 1.1.0) by newbiesup contains a reflected cross-site scripting vulnerability due to improper input neutralization during web page generation. This flaw allows attackers to inject malicious scripts that execute when a user interacts with crafted input, potentially compromising user data and application behavior. The CVSS v3.1 base score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact 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 partial disclosure of sensitive information, modification of displayed content, or disruption of availability. The scope change indicates that the vulnerability affects resources beyond the initially vulnerable component. However, no known active exploitation has been reported.
