The Nikel Beautiful Cookie Consent Banner versions up to 4.6.1 suffer from a reflected cross-site scripting (XSS) vulnerability due to improper input neutralization during web page generation. This allows attackers to inject malicious scripts that execute in users' browsers when they interact with the affected banner. The CVSS 3.1 vector indicates the vulnerability is remotely exploitable over the network without privileges, requires user interaction, and impacts confidentiality, integrity, and availability at a low level. No patch or vendor advisory is currently available to confirm remediation status.

Successful exploitation of this vulnerability can lead to execution of arbitrary scripts in the context of the affected web page, potentially allowing attackers to steal user data, manipulate page content, or perform actions on behalf of the user. The CVSS vector indicates low-level impacts on confidentiality, integrity, and availability. No known exploits in the wild have been reported.

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