The roninwp FAT Event Lite plugin versions up to 1.1 suffer from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows attackers with at least low privileges and requiring user interaction to inject malicious scripts that execute in the context of other users. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, scope changed, and low impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to information disclosure, session hijacking, or other actions limited by the medium severity rating. The impact includes limited confidentiality, integrity, and availability effects as indicated by the CVSS vector. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting plugin usage to trusted users only and monitor for suspicious activity related to script injection. Avoid exposing the plugin to untrusted users where possible.
