The adamskaat Scroll Top plugin (version 1.3.3 and earlier) suffers from a reflected cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows attackers to inject malicious scripts that can execute in the context of the victim's browser. 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 impacts on confidentiality, integrity, and availability. No patch or vendor advisory is currently available, and no known exploits have been reported.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of a victim's browser, potentially leading to information disclosure, modification of data, or disruption of service. The reflected nature means the attack requires user interaction, such as clicking a crafted link. The vulnerability affects confidentiality, integrity, and availability to a limited extent.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
