What the vulnerability does
The RSS Aggregator plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'template' parameter in all versions up to, and including, 5.0.10 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
The RSS Aggregator plugin for WordPress contains a cross-site scripting (XSS) vulnerability in versions up to 5.0.10. An attacker can inject malicious scripts into RSS feeds that execute in the browsers of site visitors and administrators. The vulnerability affects the scope beyond the plugin itself, potentially compromising user sessions and site data. Update to a version newer than 5.0.10 to remediate.
What an attacker can do
Inject malicious JavaScript into RSS feeds that runs in visitors' browsers and steals session data or credentials.
Potential impact on your site
