Name of the Vulnerable Software and Affected Versions WP RSS Aggregator versions prior to 4.20

Description The issue arises from the lack of sanitization and escaping of the id parameter in the "wprss fetch items row action" AJAX action, leading to a Reflected Cross-Site Scripting issue. This allows for potential malicious script injection when the parameter is outputted back in the response.

Recommendations For versions prior to 4.20, update to version 4.20 or later to resolve the issue. As a temporary workaround, consider restricting access to the "wprss fetch items row action" AJAX action to minimize the risk of exploitation. Avoid using the id parameter in the affected AJAX endpoint until the issue is resolved.
