GhostPool Aardvark versions up to 4.6.3 are affected by a reflected XSS vulnerability due to improper input neutralization during web page generation. This allows attackers to inject malicious scripts that can execute in users' browsers, potentially leading to information disclosure, session hijacking, or other impacts typical of reflected XSS. The vulnerability is remotely exploitable without privileges and requires user interaction. The CVSS 3.1 vector indicates 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 could allow attackers to execute arbitrary scripts in the context of affected users' browsers. This may lead to information disclosure, session hijacking, or other client-side impacts. The vulnerability affects confidentiality, integrity, and availability to a low degree but is considered high severity due to ease of exploitation and scope change.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, users should exercise caution with untrusted input and consider implementing web application firewall (WAF) rules to detect and block reflected XSS attempts if possible.
