CVE-2022-4667

Name of the Vulnerable Software and Affected Versions The RSS Aggregator by Feedzy WordPress plugin versions prior to 4.1.1

Description The issue allows users with a role as low as contributor to perform Stored Cross-Site Scripting attacks, which could be used against high privilege users such as admins. This is due to the plugin not validating and escaping some of its block options before outputting them back in the page.

Recommendations For versions prior to 4.1.1, update to version 4.1.1 or later to resolve the issue. As a temporary workaround, consider restricting the use of the block options to minimize the risk of exploitation.
