This vulnerability (CVE-2026-57344) is an unauthenticated cross-site scripting (XSS) issue in RadiusTheme's Classified Listing product, affecting versions up to 5.4.2. It stems from improper input neutralization during web page generation (CWE-79). The CVSS 3.1 base score is 7.1, indicating high severity, with network attack vector, low attack complexity, no privileges required, user interaction required, and scope changed. The impact includes partial loss of confidentiality, integrity, and availability. No known exploits in the wild or vendor patches have been reported as of the publication date.

Successful exploitation of this vulnerability could allow an unauthenticated attacker to execute arbitrary scripts in the context of the affected web application. This may lead to partial compromise of user confidentiality, integrity of data, and availability of the service. The CVSS vector indicates that user interaction is required and the attack can be performed remotely without privileges.
