WordPress Richview Zero Day Vulnerability
Severity Rating: High
A vulnerability has been identified in WordPress plugin Richviews, which can be exploited by remote attackers to deliver stored cross-site scripting (xss) payloads. The vulnerability exist because of two core issues in the Rich Reviews. The first one is a lack of access controls for modifying the plugin’s options, and secondly is a subsequent lack of sanitization on the values of those options. Consequently, this can result in malvertisements being injected, causing pop up ads and redirects to appear on the site using the plug-in.
The vendor has discontinued all active support and development of Richviews. Users are advised to remove the plugin from their sites immediately
