## Technical details

The Classified Listing plugin for WordPress (versions <= 5.4.2) is vulnerable to Unauthenticated Cross-Site Scripting (XSS) due to improper neutralization of user-supplied input during web page generation (CWE-79). An unauthenticated remote attacker can exploit this by tricking a user into clicking a malicious link or visiting a crafted page. Because the vulnerability is 'unauthenticated' and has a 'changed' scope in the CVSS vector, it allows for the execution of arbitrary JavaScript in the victim's browser session, which can lead to session hijacking or unauthorized actions on behalf of the user. The issue is fixed in version 5.4.3.

## Affected products

- RadiusTheme Classified Listing <= 5.4.2
