This vulnerability in PluginOps MailChimp Subscribe Forms (<= 4.1) allows stored cross-site scripting due to improper input neutralization during web page generation. An attacker with low privileges can inject malicious scripts that execute when other users view the affected content, potentially leading to partial compromise of confidentiality, integrity, and availability. The vulnerability requires user interaction and is remotely exploitable over the network.

Successful exploitation could allow attackers to execute arbitrary scripts in the context of the affected site, potentially leading to data theft, session hijacking, or disruption of service. The CVSS vector indicates low attack complexity, low privileges required, and user interaction needed, with impacts on confidentiality, integrity, and availability rated as low to high respectively.

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