AI Analysis
Technical Summary
The WPeMatico RSS Feed Fetcher plugin for WordPress, in versions prior to 2.8.27, fails to properly sanitize RSS feed content before saving it as post content. This vulnerability enables users with Contributor or higher privileges to perform stored Cross-Site Scripting (CWE-79) attacks by injecting malicious scripts into feed content that is later rendered in the WordPress site context.
Potential Impact
An attacker with Contributor or higher privileges can exploit this vulnerability to inject malicious JavaScript code that will be stored and executed in the context of other users viewing the affected posts. This can lead to session hijacking, defacement, or other client-side attacks. The vulnerability does not affect users without sufficient privileges to create or edit posts.
Mitigation Recommendations
Upgrade the WPeMatico RSS Feed Fetcher plugin to version 2.8.27 or later where this issue is fixed. There is no indication of an official patch advisory provided here, but the version boundary clearly indicates remediation in 2.8.27. Until upgraded, restrict Contributor role permissions or avoid importing untrusted RSS feeds.
