The RadiusTheme Radius Blocks plugin for WordPress versions up to 2.1.2 contains a stored cross-site scripting vulnerability (CVE-2024-54272) due to improper input neutralization during web page generation. This flaw allows attackers with at least low privileges and requiring user interaction to inject malicious scripts that can execute in the context of other users, potentially leading to partial confidentiality, integrity, and availability impacts. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and scope change with low impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can lead to stored XSS attacks, which may allow attackers to execute arbitrary scripts in the browsers of users who view the affected content. This can result in partial compromise of user confidentiality, integrity, and availability, such as session hijacking or unauthorized actions performed on behalf of users. However, the attack requires user interaction and low privileges, limiting the ease of exploitation. No known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting user input that can be rendered by the plugin or applying web application firewall (WAF) rules to detect and block XSS payloads related to Radius Blocks. Monitor vendor channels for updates and apply patches promptly once released.
